Whatever is worth doing at all is worth doing well.

Anything worth doing, is worth doing right.

More and more it seems to me that about the best thing in life is to have a piece of work worth doing and then to do it well.

A thing worth learning is worth learning well.

The reward of a thing well done is having done it.

If a thing's worth doing, it's worth overdoing. (Lazarus Long)

Doing well is a result of doing good.

What is worth having is worth working for.

To know how to do something well is to enjoy it.

Anything worth achieving is worth overachieving.

If you are going to do something, do something that matters.

Anything worth doing is worth doing poorly — until you can learn to do it well.

"WHATEVER YOU DO, DO IT WITH ALL YOUR MIGHT Work at it, if necessary, early and late, in season and out of season, not leaving a stone unturned, and never deferring for a single hour that which can be done just as well now. The old proverb is full of truth and meaning, "Whatever is worth doing at all, is worth doing well." Many a man acquires a fortune by doing his business thoroughly, while his neighbor remains poor for life, because he only half does it. Ambition, energy, industry, perseverance, are indispensable requisites for success in business. Fortune always favors the brave, and never helps a man who does not help himself."

Anything worth doing is worth doing slowly.
