Be not as one that hath ten thousand years to live; death is nigh at hand: while thou livest, while thou hast time, be good.

Practice really hearing what people say. Do your best to get inside their mind.

Do not waste what remains of your life in speculating about your neighbors, unless with a view to some mutual benefit. To wonder what so-and-so is doing and why, or what he is saying, or thinking, or scheming -- in a word, anything that distracts you from fidelity to the ruler within you -- means a loss of opportunity for some other task.

Our wills are ours, to make them Thine.

Just as nature takes every obstacle, every impediment, and works around it--turns it to its purposes, incorporates it into itself, so, too, a rational being can turn each setback into raw material and use it to achieve its goal.

Even while a thing is in the act of coming into existence, some part of it has already ceased to be.

Dwell on the beauty of life. Watch the stars, and see yourself running with them.
