Be gentle and civil with your thoughts, they were born out of your probability matrix. Most of it is just randomly calculated and streamed survival information to your conscious. Getting angry at a thought is like yelling at the teller at a bank, instead of asking for the manager.
(when you go to make a painting) "you'll have a thought, but dont get stuck there. Youll always have one thought, but you should be able to make two, and youre really getting somewhere if you can make three!" -my painting teacher
