One gives twice who gives quickly. One can never repay one's debt to one's mother. One is equally indebted to one's teacher and to God. Open your eyes, not your mouth. Part with your head, but not with your secret.
Patience is bitter, but it bears sweet fruit.
Stairs are climbed step by step. Stretch your feet according to your blanket. Study from new books but from old teachers. The devil takes a hand in what is done in haste. The miser and the open-handed spend the same in long run.
