Advice doesn't cost anything - unless you follow it.

Nothing is given so profusely as advice.

There's no such thing as advice to the lovelorn. If they took advice, they wouldn't be lovelorn.

Nowadays people know the price of everything and the value of nothing.

On one level, wisdom is nothing more profound than an ability to follow one’s own advice.

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

ideas are worth nothing unless executed

Of little worth as life is when we misuse it, it is worth that effort. It would cost nothing to lay down if it were not.

If a book gives you only one good piece of advice, it’s already worth your time.

Knowledge has no value except that which can be gained from its application towards some worthy end.

If you do not take risks for your opinion, you are nothing.

Conventional wisdom is nothing to me but a reference point.

I understand what you're saying, and your comments are valuable, but I'm gonna ignore your advice.

I don't advise. You mutn't give any weight to what I say, except in so far as your own judgment approves it.
