They say show me your friend and I will tell you who you are. And that is definitely true the people you surround yourself with really influence you and you can't change the fact.
If you definitely surround yourself with devils you will become the next devil, but if you surround yourself with Angels you will become the next angel. Watch the freinds you keep because they will really alter your life knowingly or unknowingly.
Surround yourself with the best people if you want to be the best.
