“Doing what needs to be done may not make you happy, but it will make you great.”

“If you cannot get rid of the family skeleton, you may as well make it dance.”

“If you take too long in deciding what to do with your life, you'll find you've done it.”

“Thus, I blush to add, you can not be a philosopher and a good man, though you may be a philosopher and a great one.”

“Happy is the man who can make a living by his hobby”

“Do not do unto others as you would that they should do unto you. Their tastes may not be the same.”

“This is the true joy in life, the being used for a purpose recognized by yourself as a mighty one; the being thoroughly worn out before you are thrown on the scrap heap; the being a force of Nature instead of a feverish selfish little clod of ailments and grievances complaining that the world will not devote itself to making you happy.”
