Simple trick to get rid of negative thoughts.

I've discovered this trick a few days ago and it's really simple.

Everytime you start having negative thoughts just sing a song in your head (or out loud, if you are somewhere, where you can do this). This is just a simple distraction but it works wonders.

Trying to supress negative thoughts is hard. You need to give your brain something else to process so it won't focus on the bad thoughts.
