I have been reading up a bit on self confidence as I have had a rather difficult time at work thats left my tank empty and I came across this... I am going to try this and I will report back!!! try it too, lets see if it works....
When you are running, your mind will start to say, “This is too hard. I want to stop and go and watch TV / drink wine /other.”
This is negative self-talk, and there is a trick that can change everything .... imagine that a negative thought was a bug, be vigilantly be on the lookout for these bugs. When you catch one, stomp on it (mentally of course) and squash it. Kill it dead. Then replace it with a positive one. (“C’mon, I can do this! Only one mile left!”).
