If you want to go somewhere, it is best to find someone who has already been there. Nothing is given so freely as advice. Those who live in glass houses should not throw stones. Never give advice unasked. He who builds according to every man's advice will have a crooked house. Take help of many, counsel of few. The best advice on the art of being happy is about as easy to follow as advice to be well when one is sick. The best time to give advice to your children is while they're still young enough to believe you know what you're talking about. Never tell your problems to anyone, 20% don't care and the other 80% are glad you have them. If you want to make the wrong decision, ask everyone.
