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

Things themselves cannot touch the soul, not in the least degree, nor have they admission to the soul nor can they turn or move the soul: it turns and moves itself alone and whatever judgment it may think proper to make, such it makes by remaking for itself the things that present themselves to it

Turn thy thoughts now to the consideration of thy life, thy life as a child, as a youth, thy manhood, thy old age, for in these also every change was a death. Is this anything to fear?

Be not disgusted, nor discouraged, nor dissatisfied, if thou dost not succeed in doing everything according to right principles; but when thou bast failed, return back again, and be content if the greater part of what thou doest is consistent with man's nature, and love this to which thou returnest

No one wearies of benefits received.
