Why I work out.

This.  


This is why I work out.  This is why I do endurance events.  Because I've learned that just when I think I cannot go one more step, or pedal that bike one more stroke, if I simply take the next step, pedal the next stroke, I can do so much more than I ever thought I could.  It hurts, oh yes, it hurts, but the pain is nothing compared to the feeling of exhilaration and accomplishment.  And knowing that if I can just finish, there is nothing I cannot do.  I am successful in business because I am successful on the field.  It's quite simply, amazing.
