I don't believe in this at all, because of some failure only then some one is going to start working back? I believe it is created during one's young years as a child, people saying no you can't for one reason or another, you either sit there and accept or you revolt and show them they are wrong. Most people in USA are couch potatoes that "make a living" who rather watch other's struggle to "make a life", you persevere when all you see nothing but walls knowing you can find the path of less traveled, you know that truth is the hardest chose but it is easiest to remember but it takes longer to accomplish, and duck tape are for those who think it best way to make fixes when they too lazy to spend time to correctly fix.
I deal with pain daily, seldom take meds for pain, but I see pain as a reward for more time to accomplish more in my life, it is when you don't have pain-you will worry that it has gone dead. But various pains with either give you more in life or take away all that you are, depends on you.
