Failure expresses itself constantly as an excuse, a reason to stop, an obstacle you have never seen, a barrier bigger than ever existed. Failure is constantly there, presenting itself as a comfortable option, an excuse, a good excuse, the best excuse you could state: "I have never done that before." Even better: "no one has done that before." Who can argue that?

Presumptuous you, thinking you might be better than all that came before? No, give up now rather than risk wasted effort, that is the lure presented by failure.

Success is a challenge, a distant picture in your mind, blurry, indistinct. Who knows if it could be done? Success could be just past the next bend, just over a little hill, a small rise, some little effort all that remains, BUT YOU DON'T KNOW.

Success could be a mirage, ever distant, a goal to pursue like Don Quixotic's, never to be achieved. Do you want a wasted life spent pursuing some ephemeral dream? Give up now! Pursue something you KNOW you can achieve and be ever mediocre, average, one of the crowd.
