Don't let petty stuff bother you. Become numb to the dumb stuff and don't let it penetrate your spirit.
Negativity?
Dumb.
Gossip?
Dumb.
Jealousy?
Dumb.
Pettiness?
Dumb.
But then again so is self doubt and a lack of confidence. Why wouldn't you be your biggest champion and support? Numb it when that nagging negative inner critic tries to convince you that you are less than the star you are intended to be! When you tell your self negative message who needs others! That's less work for them!
Numb the dumb both internally and externally. Focus on choosing to feel the good in your life. After all, it is your choice!
