Working more than 40 hours a week doesn’t mean you’re working hard. It just means you are working more than 40 hours a week.
There's an epidemic of interruption out there. No wonder people have to put in 60+ hours a week just to get 40 hours worth of work done.
It’s amazing how much mediocrity you’ll tolerate in your own work, and how little you tolerate in someone else’s.
The best way to get things done is to have fewer things to do.
