Love this quote from 37signals:
But you don’t have to work superhuman hours. A normal workweek should be plenty. Even less is ok. In fact, being short on time is a good thing. It forces you to focus on the essentials. There’s no time for things that don’t matter. There’s only time for the basics. And if you want to build something great, you have to nail the basics first.
More time isn’t always better. In a job that’s flexible, I have to constantly remind myself to get stuff done and move on. Not so I can waste time later or skip out early, but so I can focus on what matters.
