If everyday you keep getting better, you end up being the best.

A challenge to improve yourself is the greatest of all challenges you will ever face.

Occasional criticism is better than the constant admiration.

Accept both criticism and compliments because a rainbow needs both sun and rain to reveal itself.

Don't overestimate yourself because of compliments and don't underestimate yourself because of criticism.

Don't let appreciation get to your head and don't let objections get to your heart.

Those who make excuses, don't make progress.
