1. Work (or, for the retired & students, Projects You Do For Others)
Yes, yes, indeed, the time has come to slap down that project which nags at you most and which it will relieve you greatly to have completed. Don't let it take over your day if it would cause you other issues, but do put in at least 30 minutes moving that horrid old festering project closer to out of your life.
Clean up/get rid of/pass along one of the projects you drew a dotted line through on your list yesterday. Cross it off thoroughly now.
Reward yourself with a little chunk of time working on one of your starred projects. Even if you only have time to look at it and write down a little list of what you want to do next, that's great. Thinking about a fun project as you head off to bed is nice.
