Everyone is a threat, and anyone can be beat at any given moment. No one is invincible.
Everyone in life faces obstacles. That's what made me who I am. I don't regret to have been bullied because probably if I would not have faced those obstacles I would not have been the man that I am. It make my stronger in a way and it helped me to forge the person that I am right now.
Once fear enters your life - it will take you in one of two directions: empowerment or panic.
Only way to eliminate the element of surprise is to know yourself and now your adversary.
