What comes to mind is the saying 'if you can't take the heat stay out of the kitchen'. I think of this constantly when hearing about people who want something (YC, acting, medicine, sports, music career, endless list) but then for some reason aren't built to take the punishment (that others are). There are some people that can take the punishment (if you want to call it that) and not miss a beat. Just like there are people that can climb mountains, race cars, play football, run marathons and live off in the jungle. This idea that everyone should be suited for anything is just not correct. And don't think 'well I won't know so why not try?'. Most people have some basic idea of what they are cut out for and can do and tend to stay away from (smartly) things that aren't for them.
