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.

Our wills are ours, to make them Thine.

Keep constantly in mind in how many things you yourself have witnessed changes already. The universe is change, life is understanding.

Nothing happens to any man which he is not formed by nature to bear. The same things happen to another, and either because he does not see that they have happened or because he would show a great spirit he is firm and remains unharmed. It is a shame then that ignorance and conceit should be stronger than wisdom.

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.

Always follow these two rules: first, act only on what your reasoning mind proposes for the good of humanity, and second, change your opinion if someone shows you it's wrong. This change of mind must proceed only from the conviction that it's both correct and for the common good, but not because it will give you pleasure and make you popular.

Don't let your imagination to be crushed by life as a whole. Don't try to pictures everything bad that could possibly happen. Stick with the situation at hand. ...Then remind yourself that past and present have no power over you. Only the present.
