That's my gift. I let that negativity roll off me like water off a duck's back. If it's not positive, I didn't hear it. If you can overcome that, fights are easy. (George Foreman, Preacher, entrepreneur and the oldest man to ever win the Heavyweight boxing championship of the world)
Always concentrate on the positive because if a person does not negativity will cause one to not perform or do anything constructive. Feeling sorry for oneself will not take away negative feelings. Taking action towards positive outcomes will cause negativity to pass by.
