Write it Down
The most basic habit to get into is also the most reliable. "Take notes. Write it down," says Healy. "If you want to remember where you put something, use external aids, because one of the most serious problems with memory is proactive interference." That's the idea that learning old lists (like where you put your car keys yesterday) hurts you when learning new lists (where you put them today), especially when the situations are similar. "That's the case for when you're trying to remember where you parked your car, or where you left your glasses," says Healy. "It's the best external device you can use and, it doesn't take rocket science to start doing it."
