Read Proverbs 28:26

This may shock you, but 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's no barrier too high, no valley too deep, no dream too extreme, no challenge too great for me.

Yet, we must admit that we spend more of our time concentrating and fretting over the things that can't be changed in life than we do giving attention to the one thing that can, our choice of attitude.
