Yesterday’s home runs don’t win today’s games.

Babe Ruth

When everything seems to be going against you, remember that the airplane takes off against the wind, not with it.

Henry Ford

Charles F. Kettering

Don't watch the clock; do what it does. Keep going.

Confucius

Persistence can change failure into extraordinary achievement.

Matt Biondi

Asking in faith requires honesty, effort, commitment, and persistence.

David A. Bednar

Gever Tulley

Success is the result of perfection, hard work, learning from failure, loyalty, and persistence.

Colin Powell

Throughout human history, in any great endeavour requiring the common effort of many nations and men and women everywhere, we have learned - it is only through seriousness of purpose and persistence that we ultimately carry the day. We might liken it to riding a bicycle. You stay upright and move forward so long as you keep up the momentum.
