Negative thoughts are not good. They breed easily from one another.
They grow cancerous and dangerous.
What you need to do is to replace every negative thought with a positive one.

I think I can.
I think I can.
I know I can!
I know I can!
As Curt mentions:
"You are what you think, so think what you want yourself to be."
