Think about the past seven days, I'll give you a couple of minutes right now. Just write down roughly where you think most of your time goes. Is it like strategy sessions, watching TV, drinking, partying, traveling? You should have a pretty good idea. There's no end to optimization. The best optimizations are the ones when you swear you're as efficient as you can possibly get and then you still throw out 80% of the shit you're doing. That's when you're getting into the good stuff.
