Persistence

When you make a mistake, don't look back at it long. Take the reason of the thing into your mind and then look forward. Mistakes are lessons of wisdom. The past cannot be changed. The future is yet in your power.

Be patient toward all that is unsolved in your heart and try to love the questions themselves like locked rooms and like books that are written in a very foreign tongue. Do not now seek the answers, which cannot be given you because you would not be able to live them. And the point is, to live everything. Live the questions now. Perhaps you will find them gradually, without noticing it, and live along some distant day into the answer.

Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.

Ten thousand fools proclaim themselves into obscurity, while one wise man forgets himself into immortality.

Great ability develops and reveals itself increasingly with every new assignment.

Character cannot be developed in ease and quiet. Only through experience of trial and suffering can the soul be strengthened, ambition inspired, and success achieved.
