I recently shared my tip of making a list just so I can cross the items off and asked for your best productivity bets. GirlOverboard shared a goodie.
I love lists, too, but I'm constantly losing them (usually to the wash or my messy desk). While I do my best day-to-day planning with a physical pencil-and-paper planner, my lists are kept on my iPhone. I use Toodledo and, at the risk of sounding like an ad, I absolutely love it! It helps me prioritize based on date and importance and I can split tasks up into folders. It helped keep me sane through planning my wedding!
