Those people who can't be around negative people without turning into one are just weak people. That does not mean one should be surrounded by them. Just you should always be able to maintain your own path not follow the crowd down the shit shute. These times are our lessons in life of what not to be and teach us to rise above. Once we learn how to rise above we should never lower our standards to be just like everyone else, no matter who we are around. You don't have to consider yourself a leader to lead by example. Others also follow the standards of the crowd. Up or down. Same thing no different just opposite ends of the scale.
