It is the greatest mistake to think that man is always one and the same. A man is never the same for long. He is continually changing. He seldom remains the same even for half an hour.

From my point of view, he can be called a remarkable man who stands out from those around him by the resourcefulness of his mind, and who knows how to be restrained in the manifestations which proceed from his nature, at the same time conducting himself justly and tolerantly towards the weaknesses of others.

Sincerity is the key which will open the door through which you will see your separate parts, and you will see something quite new. You must go on trying to be sincere. Each day you put on a mask, and you must take it off little by little.

There do exist enquiring minds, which long for the truth of the heart, seek it, strive to solve the problems set by life, try to penetrate to the essence of things and phenomena and to penetrate into themselves. If a man reasons and thinks soundly, no matter which path he follows in solving these problems, he must inevitably arrive back at himself, and begin with the solution of the problem of what he is himself and what his place is in the world around him.

Every grown-up man consists wholly of habits, although he is often unaware of it and even denies having any habits at all.

He who has gotten rid of the disease of "tomorrow" has a chance of achieving what he is here for.

What you need to know is very little, but to know that little takes very very much.
