One thing you can do is to take an affirmation like "great things always happen to me" and write it out and post it everywhere you go, even on the rear view mirror of the car. You are faced with it every place you go. At first you will have resistance to this but at some point the resistance will break down and you will just accept it. Great things will always happen to you.
Then you'll probably look for other and better affirmations to use.
