I believe the single most significant decision I can make on a day-to-day basis is my choice of attitude. It is more important than my past, my education, my bankroll, my successes or failures, fame or pain, what other people think of me or say about me, my circumstances, or my position. Attitude keeps me going or cripples my progress. It alone fuels my fire or assaults my hope. When my attitudes are right, there is no barrier too high, no valley too deep, no dream too extreme, no challenge too great for me.
