I recently have been doubting whether certain girls were attracted to me so I have found a very effective way of reminding myself that I am a studmuffin
This method takes no more than an hour (edited for esperanto

) and is pretty much foolproof. All you do is take a small piece of paper that can fit in your wallet and write down all the girls that you think have ever been attracted to you, including ex-girlfriends, crushes, ect, extending all the way back to the beginning of high school. The only girls you don't write down are the ones that you had bad experiences with. Keep this in your wallet so it will be a bathroom-trip away if you are second-guessing yourself.
