Have the wisdom to know what cannot be changed, and the strength to change what can.

Don't be concerned with other people's impressions of you. They are dazzled and deluded by appearances. Stick with your purpose. This alone will strengthen your will and give your life coherence.

I laugh at those who think they can damage me. They do not know who I am, they do not know what I think, they cannot even touch the things which are really mine and with which I live.

By accepting life's limits and inevitabilities and working with them rather than fighting them, we become free.

No living being is held by anything so strongly as its own needs.

Nothing truly stops you. Nothing truly holds you back. For your own will is always within your control.

To know that you do not know and to be willing to admit that you do not know without sheepishly apologizing is real strength and sets the stage for learning and progress in any endeavor.
