Lincoln Mullen, writing for ProfHacker, offers useful advice on how (and why) you can make some things in life more difficult and complicated. This one hit close to home for me:

I’ve decided to wait 24 hours before agreeing to do anything that is more than routine. Usually, if you ask me to do something, and I’ll say yes right away and regret it later. So now I wait a day before thinking about it, so that I actually can think about it.

I will try to remember that next time.
