Little things and big problems
You don’t have time to bother about all the little things of your start-up. Don’t pretend to control everything nor develop everything as if it was the last thing you’d do in life. It’s impossible. Just deliver on time. There are lots of minor things that can be delayed or even ignored, whereas other issues that might arise impact deeply in the competitive advantage of your venture. If you spend your time in those small unimportant issues, your head will deviate from the correct path, so it’s risky.
Tackle the big issues. Forget the little things. Forever. You will be happier. And healthier.
