Perfection vs. Good Enough
One of the most salient changes I've had to make in the transition from ballet <> company building is that of shifting from a mindset focused on perfection to one focused on good enough in order to move faster.
Ballet requires you to be almost superhumanly meticulous from a very young age. Doing things sloppily early on leads to permanently incorrect physical "placement" (how you align your ankles, knees, and hips), which down the line sets the stage for serious injuries and poor technique that is almost impossible to reverse later in life. Doing things correctly before the age of 10 is critical to building good physical habits. That meticulousness follows you for the rest of your career.
While attention to detail is generally a good thing, foundering requires a re-prioritization of speed and decision making over correctness. Breaking this default mindset has been one of the toughest but also most rewarding aspects of building. Realizing that it's *actually OK* to make some wrong decisions, so long as they're reversible - which most are - liberates you to make many more of them.
I'd argue that part of the reason "excellent" students – those who get perfect grades – often struggle (or simply never pursue) being founders is precisely because they've internalized a perfection rather than a good enough mindset.
Life is in most ways a game of the latter path. A few decisions really matter and most other things sum to a rounding error. Building intuition for how to optimally allocate energy to decisions is in my experience an elusive superpower and lifelong quest worth pursuing.
