Actually there are no positive and negative thoughts. Thoughts are simply continuous stream of self talk - kind of chatter that you hear from "walk-talkie" from a say ... traffic cop.
General view is that any thought that makes you happy is a positive thought and the one that makes you sad - is a negative thought.
If you look deeper - thoughts are neither positive or negative. We give the label to the thoughts depending upon how we feel at the time when thought comes to our mind.
What is the proof ?
1. Given a thought - different people feel differently in terms of tone (happy or sad) and also in terms of intensity. So there is no universal positive or negative thought.
2. Travelling on a time dimension - think of a good or bad thought that came to you . say one year ago. Think - how do you feel about that though now? May be same or different - you cannot be sure. So what mattered then or matters today - some time down the line - might not matter at all. And vice versa.
One way to deal with a recurring thought is ask - will this matter 1 year from now?
Another way is to ask "Can you do something about it" ? If yes - then do or else let thought pass thru.
