Marc Andreessen, a legendary venture capitalist, helped shape some of the defining companies of the last two decades — Airbnb, Coinbase, Facebook, Skype — and has assumed the role of thought-leader. When Andreessen speaks about what it takes to succeed as an entrepreneur, people listen closely and emulate.
So, naturally, his comments on David Senra’s podcast trashing “introspection” blew up online, with Elon Musk and many others applauding. Andreessen sees “introspection” as a problem, a genuine blocker to success, because it leads us to “feel guilty” and “dwell on the past,” stagnating unproductively in fear and doubt.
For accomplished entrepreneurs like Andreesen and Musk, it seems, constant action is an imperative and “introspection” just slows them down. But do we really have to choose between stagnation induced by introspection and a life of achievement without self-knowledge?
Those who think we face this choice misunderstand introspection. In fact, it is crucial for an action-oriented and productive life to understand oneself deeply.
Introspection is the “examination of one’s own thoughts and emotions.”1 It means identifying what one knows or doesn’t, what evidence one has, what assumptions one is making, etc. It also means identifying one’s emotions and their causes, allowing one to evaluate one’s motives for action. It’s a demanding task that can easily err and must be consistently practiced. Thus, it’s a much broader and more important phenomenon than Andreessen suggests.
Andreesen makes two serious errors in characterizing introspection.
First, the idea that introspection means “dwelling on the past” falsely equates introspection with rumination, i.e., obsessing over distressing thoughts. Rumination is problematic: for instance, one might obsessively dwell on having turned down a promising job at a startup because of fear of failure. In such a case, one might repeatedly think to oneself, “I wish I had chosen differently” or “I gave into failure at that moment.” But such rumination is unhealthy introspection, since it involves dwelling on one’s mistake without a clear purpose. To properly address this mistake, healthy, purposeful introspection is needed, that is, asking if and why one acted from fear, to what extent one’s fear was justified, given what one knew at the time, and so on, in order to improve one’s choices and character going forward.
Second, introspection doesn’t mean “feeling guilty” and not doing anything about it. Some introspection generates guilt one should feel, as in the above example, if one irrationally gave into fear. Here, accepting responsibility for giving into fear helps correct the mistake that generated earned guilt, allowing one to move forward in a productive career — perhaps by seeking ambitious opportunities in the future despite feeling some trepidation at doing so. In such cases, this introspective work is not done at once but requires an ongoing process of identification and revision. If one defaults on that work, one will likely continue to act from fear and miss great opportunities.
However, guilt can be “unearned,” if it results from doing no wrong. For instance, suppose that one feels guilt for pursuing a career as an engineer when one’s parents expected one to pursue medicine. In this case, it’s crucial to examine and revise the premises that generate the unearned guilt. For example, one might identify the false premise that “one should meet one’s parents’ expectations, no matter what,” or identify that one has always had an irrational fear of disappointing one’s parents. Correcting the false premise and overcoming the fear clears the way to take proper pride in one’s career, which is crucial to sustaining it. The introspective work involved here is also crucial for a healthy relationship to one’s parents, one not dictated by fear or guilt. Such work can take years to execute correctly — and many default on this task.
By characterizing introspection as obsessively dwelling on feelings of guilt, there is a danger that what Andreesen wants is to exempt entrepreneurs from judging the morality of their own actions. But no one is exempt from this responsibility. Elon Musk should think about the truth and effect of some of what he posts online. Andreesen should think about his role in the DOJ’s persecution of Microsoft in the 2000s. To do so, and to change course and make amends when necessary, is not to pointlessly dwell on the past.
And when one looks at the careers of great entrepreneurs, one characteristic that stands out is their willingness to constantly question themselves and their ideas, at least in business.
Successful entrepreneurs need to know their purpose. For example, consider Jeff Bezos’s “regret-minimization framework,” in which he projects himself at 80 and reflects on what he would like to have done with his life.2 Bezos employed this framework early on, when he needed to identify whether working at an established hedge fund in New York was more meaningful to him than pursuing a new vision as an entrepreneur. Was his dream of entrepreneurship just a fantasy or something he could really carry out? Did he have the right temperament to deal with the massive uncertainty in entrepreneurship? Could he really be happy staying in the hedge fund world? Answering these questions required identifying his motivations, what he knew, considering what he cared most deeply about, and projecting what kind of person he wanted to become. Ultimately, this introspective work led him to refocus his life to transforming the online customer shopping experience, and channel all his efforts to that one goal.
Billionaire investor Ray Dalio practices what he calls “pain + reflection.” When painful mistakes happen, Dalio uses that pain as an opportunity for active reflection, to understand what happened and how to learn from it.3 For instance, Dalio reflected deeply when he nearly ruined himself in the early 1980s, operating on the flawed assumption that Mexican banks would default on U.S. loans. Instead of simply dwelling in shame or self-doubt, he worked to identify his flawed assumptions and better identify the state of his own knowledge. He realized that although he was right that too much money had been lent to Mexican banks, he was not in a position to predict that the outcome would be the banks defaulting on those loans. Thus, he changed his approach, carefully self-monitoring what he was actually certain of and what he wasn’t — an approach that’s impossible without introspection. His career was forever changed: He credits his masterful awareness of uncertainty in markets over time for much of his success as an investor.4
Few would consider Sam Walton (discussed in the aforementioned podcast) to be an exemplar of introspection. But if introspection is an ongoing and active self-awareness of one’s thoughts and motivations, Walton did it intensively in developing Walmart’s philosophy. He spent years studying what allowed other discount-style supermarkets to succeed or fail, and concluded that a company can lower markup while earning more with increasing volume.5 To reach this conclusion, Walton had to constantly consider whether his assumptions were warranted or not, by asking questions such as: Do I really know whether investing in distribution systems is unimportant? Do I have evidence that stores can only succeed in big cities? Am I sure that high margins are necessary for high profits? None of the answers are obvious or easy to apply. But without this introspective questioning, merely observing market conditions or taking on conventional assumptions would not have led to Walton’s distinctive approach.
There is no escape from the need to introspect. Without introspection, one consigns oneself to a life of ignorance, leaving one’s inner self a mystery. Imagine a Jeff Bezos who never asked himself what he truly wanted, a Ray Dalio who never asked himself what premise led him to his crucial error, or a Sam Walton who never questioned his (or others’) assumptions. Identifying your own knowledge and purposes, analyzing your emotions, and integrating them appropriately with action is crucial not just in business but across life. It’s through introspection that one learns from mistakes, focuses on achieving one’s deepest purposes, and builds character with integrity.
