that's a very interesting thought! honestly, i think for most people, the biggest enemy would be yourself. there are a lot of instances where you can be your own worst enemy, and certain thought processes can lead to your downfall. a single thought can tank your confidence if you believe it--and depending on what that thought it, the lack of confidence could keep you from trying new things that could change your life for the better.

this is certainly not saying that people are incapable of having enemies. i'm sure that people do, but at the end of the day it's you vs the world, because you're the writer of your own story so...yeah
