A person who pretends to be unselfish is generally foolish-selfish. It is the wise-selfish who are right; they are selfish, it is true, but they are selfish with true wisdom. They think out what it is in life that will benefit them most. The foolish-selfish man never puts money by, and thus never has any to give away. The wise-selfish man will obtain money in order that he can express his generosity with what he has collected. He who remains a pauper all his life has never achieved anything for anyone. Therefore he is wise who not only understands what is real gain and what is false, but also understands the price there is to pay for the gain. What determines our success is weighing whether one's gain is of more value than the price one has to pay for it, or whether the price one has to pay is greater than the gain one can obtain. He who perceives this clearly has learnt the true business of life very well.
