I make a habit of recording unexpected work. It's helpful for avoiding feeling bad if you miss your goals (you can see why you missed it - it's easy to forget otherwise), and it's helpful for anticipating the same work in the future and understanding why you didn't expect it.
Goals all the way! Give yourself purpose, keep track, and make sure you've got a manageable work load.
During the work day, or hanging out friends and family, it’s easy to delude myself that all is well. Its hard to lie to yourself at 3:00 AM Sunday morning. Every time i sleep badly, i know it’s time to stop and take a deep look at what’s going on.
That metric has served me well so far.
- What did I work on last week?
- What do I plan to do this week?
- What were the obstacles I encountered, and what I think will hinder me this week?
