There are certain things and ideas your mind thinks up whenever you are fearful of something. It is not always jumping out of a plane or swimming with sharks either. 

It can be going to the gym, waking up earlier or making a sales call. Right when you are about to do it, you get the thought that contradicts you taking action. It might even just tell you to prolong it. 

You shouldn't. You should do it in that moment and do it for longer than you even want to. Run the extra half mile, make an additional 5 calls after you promised to only make 10. 

Outdo yourself even by your own standards. That is what Muhmmed Ali used to say. He only counts the sit ups once he wants to quit. Those are the only ones that matter.
