Here’s a bunch of short term reminders at Lifehacker.

Here are the ones I use regularly:

• Put a note with my keys
• Put a note sticking out of my billfold
• Put the object I want to take with me on the floor by the door I use most often
• Email myself
• Voicemail myself
• Put an ordinary object in an unusual place (what’s that doing there? Oh, yeah!)
• If I need to run an errand on the way home from work – I’ll put a piece of paper over the speedometer.

What works for you?
