One practice that unquestionably causes happiness is completing tasks that are hanging over your head. When I was at my last job, failing to do that was my biggest cause of anxiety. Leo Babauta has a post today on Zen Habits on the topic, where he advocates having a One Thing to-do list. Just having that one looming task to do forces you to do it first, instead of procrastinating with other less important items. In my training for PIRG, that exact advise was one of the biggest messages of their productivity workshop. Do the thing you’re most dreading first thing in the morning.

So today, my One Thing is calling Amtrak to figure out the cheapest way to get tickets for my cross-country trip. Then I can buy the tickets and not stress out anymore about the price going up. What’s your One Thing today?
