Success is when you set out to complete a goal and you accomplish or at least attempt it one of my favorite quotes is "you miss 100% of the shots you don't take" I like it because it says if you don't try it is just as bad as failing.

Failure for me is when you try to complete a goal and you fall just short of completing a goal but with failure at least you attempted it and that counts for something.

With the influence of success and failure you tend to not want to attempt something with the fear of failing in your head so it sways if you want to attempt it our nah.
