I am careful not to confuse excellence with perfection. Excellence, I can reach for; perfection is God's business.
Michael J. Fox

Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb.
Sir Winston Churchill

The man who has no imagination has no wings.
Muhammad Ali
