When you focus on a thought on a constant bases, whether positive or negative. External forces drive you into doing things you might not normally do.
Another armed robber rightly said "i don't steal from people. I take from them". He replaced the word STEAL for the word TAKE, of course that explained why he couldn't stop the habit even when he tried so hard.
