I call bullshit. If he thought about competitors, it obviously affected his actions. So how can he know, he would be where he is today, if he hadn't thought about competitors? This is just another Silicon Valley bullshit statement...
Yep and there are always versions of what I will call the 'deathbed' story. It usually is spoken by a person who has made it spending time on their deathbed saying they didn't have to work as hard as they did.
Not only that but what is exactly the definition of 'worry'? It means different things to different people and maybe what he did was obsessive compared to what someone else did or would do in the same exact situation.
Look I am obsessive with computer backups as much as I can. Luckily I haven't really needed them. Wouldn't it be really stupid for me to say years from now 'boy I wish I hadn't spent so much time worrying about backing up my systems?'. (Of course not and that's obvious).
