I love lists. I love making todo lists, and I love crossing things off.
My quest for a viable todo list manager has lasted years, now I finally claim success! Enter: Wunderlist, a free app that syncs between iOS devices (my iPhone and iPad) and my desktop, and if needed, even has a useable webpage front-end. You can create separate lists for work and home, and I've also added lists for several upcoming movie productions.
What's special about this? Previously I had a bunch of text documents floating around with various todos, but what inevitably happened was stuff got buried, and thus, forgotten. With Wunderlist, I can assign due dates to every task, then completely forget about it until that day. When I wake up I see my list of tasks for today, as well as any overdue tasks, and can focus on finishing those without stressing out seeing the hundreds of other upcoming things.
Anyway, I love it.
