I really love this quote!
I was one who loved to be negative all the time. It started out as being funny (internally) then it became my go to attitude. Which then spiraled out of control. My mind quickly deteriorated. Alcohol and drugs didn’t help either. But I can say that my thinking really got my in trouble.
Change the music you listen to.
Change the tv shows you watch.
Change the books you read.
Change your friends, who are positive.
It’s when I did this my life began to change for the better. I’m in the process of going to church full time. Entire psychic change is needed to fully recover.
Do you agree? What have you changed in your life? 
Thank you
