Focus on what you want
Focus on what you want instead of what you don't want.
Because of the way our mind works, when we tell it not to think of something, very often that is the very thing we can't get out of our head.
For instance, try this: Don't, think of a yellow horse with purple dots!
You probably had to create a picture or had to get a sense of what a yellow horse with purple dots might look like in order not to think about a yellow horse with purple dots.
Often we go around saying things like,
'I will not worry!'
'I will not feel sad!'
'I will not feel depressed!'
Our mind only remembers the final word or sentiment, and it can end up being like a self-fulfilling prophecy. That which we did not want has now filled our being!
So, focus on what you want...train your brain to think a little bit differently.
Give your brain this kind of food for thought:
'I do the best I can with the information I have a the time.'
'I have a choice.'
'I am learning to concentrate more easily.'
'I feel good about myself.'
'I am worth the effort.'
