Ask the readers: Your single best organizing tip or tool?

Every Monday is Productivity & Organization Day at Zen Habits.

I routinely write about my organizing tips here on Zen Habits … but today I’d like to hear from you guys.

So here’s this week’s reader question:

What’s your single best organizing tip or tool?

Just one answer per person please! :)

Also, while this question is really aimed at the more organized among you, it’s definitely open to everyone who has a great tip.

Let’s hear your tips in the comments! Thanks everyone.
