Novelty, the most potent of all attractions, is also the most perishable. - André Maurois

Choose a community to live in whose efforts lie in the same direction as your own and where there will be interest in your activities. Instead of living in conflict with your family, who in your opinion do not understand you, and in the conflict destroying your happiness and that of others, seek out friends who think as you do. If you are religious, live among believers; if you are a revolutionary, live among your own kind. You can still try to convince the skeptical, and in this you will have the support of those who are in agreement with you.

There is not one who speaks of us in our presence as he does in our absence, wrote Pascal. All affection is based on this mutual deception, and few friendships would survive if we knew what our friends were saying of us behind our backs.

Knowledge is ours only if, at the moment of need, it offers itself to the mind without syllogisms or demonstrations for which there is no time.
