- If you start the day with a clean slate, write three things you'd like to do today. Pick the one that will take the longest and do that first. This is Mark Twain's "eat a frog before breakfast" advice and I think it helps a lot.
- Install SelfControl.app and start it for 8 hours immediately when you sit down to work. No matter how in control I think I am, I'm always amazed at how my reflexes take me to some distracting website before I even realize what I'm doing. SelfControl stops this habit by blocking distracting websites and making me aware of them. (Pro tip: don't write an unblocking script)
