There are many very successful people with chronic mental health conditions that at times impair their cognition to the point of debility. Like, re-read your comment with Simone Biles in mind, who is arguably the most successful gymnast ever but did spend extensive time constantly sleeping while depressed and demotivated and broken down. Quoting her, "At one point I slept so much because, for me, it was the closest thing to death without harming myself. It was an escape from all of my thoughts, from the world, from what I was dealing with." You can't deny that Vincent van Gogh, Kurt Cobain, Virginia Woolf, Robin Williams, Marylin Monroe, Chester Bennington, Ernest Hemmingway and many others were successful despite their struggles, and those are just those for whom those internal struggles resulted in something obvious to the public. For physical issues, there's Avicii who got quite successful while touring with many serious health problems. In the field of business we have to remember that for currently active entrepreneurs there are strong incentives to hide any issues (e.g. Elon Musk has years earlier admitted struggles with depression and/or bipolar disorder, but IMHO we won't get reliable information about their extent until after he retires or dies), but there are earlier examples like Ted Turner, founder of CNN; and of course there's the famous case of Aaron Swartz as a cofounder of Reddit. Here's a study https://www.michaelafreemanmd.com/Research_files/Are%20Entrepreneurs%20Touched%20with%20Fire%20(pre-pub%20n)%204-17-15.pdf https://www.michaelafreemanmd.com/Research_files/Are%20Entre... showing that entrepreneurs have a higher rate of mental health conditions than the general public. So I believe that your argument is based on false expectations.
