The reason I am not a good business executive is the same reason I’ve never been wealthy despite being rather clever and possessing the capacity for extremely hard work: I just don’t care about money, capital or profit. I only care about doing interesting and useful things - the interesting part is for me, the useful part is for everybody else. I refuse to do boring, useless things even if it’s the only way to earn a decent living. Consequently, I often don’t earn a decent living. But at least my life and work are never boring.
