Thought management can be a motherfucker.
It's so easy. Think positive and you'll be happy. If you hear a negative thought don't engage it let it disappear as quickly as it appeared. Or you can challenge it and think "no, I am not" then do some type of activity to reinforce your position.
It is beyond amazing that we can tell ourselves "I'm just _____ type of person" and let it consume our true identity. Negative thoughts can become a mantra and make you feel just as bad as positive thoughts can make you feel good.
It's can be frustrating for someone with a hard head. "You mean it's that easy?" Instead of walking up thinking "I hate me life" you can say something else even if you don't believe it and you'll feel better. " it's too easy...my life is far more complicated than that" I would tell myself, then I'd believe it.
I was practicing this the whole time except I was doing it all wrong. How could it be so easy? My old self would have typed "how could I be so stupid?"
Seriously, you can think "stupid, stupid, stupid me" and make yourself dumber for a moment. Do it enough times and you may miss the message.
