Stubbornness destroys good advice.
Never make a decision in anger and never make a promise in happiness.
Whoever wants to be a leader should educate himself before educating others. Before preaching to others he should first practice himself. Whoever educates himself and improves his own morals is superior to the man who tries to teach and train others.
Be like a flower that gives its fragrance even to the hand that crushed it.
A man is hid under his tongue.
The best revenge is to improve yourself.
