Self-perception is an interesting concept, we all strive to put on our best and show the world that we are up for anything and ready to accomplish any task is put in front of us. So why do we all have inner demons that we would much rather let play out our lives for us, but don't allow it to happen?
I have two drastic and distinct personalities, one part of me has grown and developed as I have matured and the other that I let out when I am usually by myself or those closest to me.
Growing up I was the runt and picked on, graduating high school at 5'7" and 120 LBS, this resulted in the creation of a very non-social person with no self-esteem.
it wasn't until I was on an LDS mission that I grew in confidence and stature, and that I became extroverted, outgoing and gregarious.
It is easy to judge someone based on appearances, but until you get to know someone you never know who they are or what they have gone through.
