Way to go! Some miscellaneous musings:
Your opponent, in the end, is never really the player on the other side of the net, or the swimmer in the next lane, or the team on the other side of the field, or even the bar you must high-jump. Your opponent is yourself, your negative internal voices, your level of determination.
Ever tried? Ever failed? No matter. Try Again. Fail again. Fail better.
There is no failure except in no longer trying. There is no defeat except from within, no really insurmountable barrier save our own inherent weakness of purpose.
Never let a day pass that you will have cause to say, 'I will do better tomorrow.'
