Being around somebody who is negative just breeds more negativity. Being positive is just a happier place tobe.
I had to change my attitude for the better, but I do try and be optimistic towards other negative people. The more positive I am maybe it’ll do the same to them. ~ Jessica Mitchell
Don’t think too much in life 
If you let people control you 
When you stop complaining about your problems 
Grudges are a waste of perfect happiness
