Am I the only one doing this? I have a list(laminated) I keep in my bag along with my keys so no matter what I will see it and not forget about it. Its a simple list:

IN THE BACKPACK
Shirt
Pants
Underwear
Socks
Belt
Work Keys
Lock Keys
Car Keys (the horror)
2 gloves
Respro
Cell Phone
Water
Lunch
Snacks
Protein mix
Drink mix
Wallet

I check this list at night, I check it in the morning. So far I haven't forgotten a thing(knock on wood). Feel free to copy or add to it.
