Does anyone else write themselves notes in their homes to remeber to do things?

This is one I just wrote right now and hung by the door:

STOP! Do you need to take the recycling, water bottles or thrift store donations?

This is b/c my recycling isn't curbside and I need to take it into town. Also gallon water bottle refills are only 25 cents instead of buying new bottles at the water company.

What notes do people leave out for themselves? Anything inspirational, organizational, reminders?
