The fine art of listening should never be underestimated...start today...by listening to yourself.

Leaders should learn to listen and listen to learn

The best contribution one can make to humanity is to improve oneself.

We must strive for freedom if we strive for self-knowledge. The task of self-knowledge and of further self-development is of such importance and seriousness, it demands such intensity of effort, that to attempt it any old way and amongst other things is impossible. The person who undertakes this task must put it first in his life, which is not so long that he can afford to squander it on trifles.

Without struggle, no progress and no result. Every breaking of habit produces a change in the machine.

Never blame your shortcomings on your personality. You're not built that way; you are responsible of constantly rebuilding yourself and seeking perfection by finding your faults and overcoming them.
