Start up

To be a founder, you have to be world-class in something. Make sure you’re spending the majority of your time doing that thing; this is your ‘zone of genius’. Not compromising will allow you to be a valuable contributor for a much more extended period of time and avoid burnout.

Why do so many founders build things no one wants? Because they begin by trying to think of startup ideas. That m.o. is doubly dangerous: it doesn't merely yield few good ideas; it yields bad ideas that sound plausible enough to fool you into working on them.
