“To profit from good advice requires more wisdom than to give it.”

“On one level, wisdom is nothing more than the ability to take your own advice.”

“It is always a silly thing to give advice, but to give good advice is absolutely fatal.”

“A good prescription is still more profitable than an absolution.”

“I daresay one profits more by the mistakes one makes off one's own bat than by doing the right thing on somebody's else advice.”

“And perhaps there is no advice to give a writer more important than this: — Never write anything that does not give you great pleasure.”

“But goodness alone is never enough. A hard, cold wisdom is required for goodness to accomplish good. Goodness without wisdom always accomplishes evil.”

“Avoid taking advice from someone who gives advice for a living, unless there is a penalty for their advice.”

“To be good and lead a good life means to give to others more than one takes from them.”

“Good advice is always certain to be ignored, but that's no reason not to give it.”
