One must learn by doing the thing, for though you think you know it, you have no certainty until you try.

For the things we have to learn before we can do them, we learn by doing them.

We learn by doing.

You learn by trying, making mistakes, correcting and trying again and again until your reach the desired goal, which is rarely without effort, but is rather a reward for hard work.

To learn something new, you need to try new things and not be afraid to be wrong.

You don't know what you can get away with until you try.

I am always doing what I cannot do yet, in order to learn how to do it.

Life is about not knowing and then doing something anyway.

IT is a very old saying that you never can tell what you can do until you try. The more I see of life the more I am convinced of the wisdom of that observation.

We absolutely must leave room for doubt or there is no progress and there is no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty. People are terrified — how can you live and not know? It is not odd at all. You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don't know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.

You never really know something until you teach it to someone else.

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

Don't learn to do, but learn in doing.

The way to learn to do things is to do things. The way to learn a trade is to work at it. Success teaches how to succeed. Begin with the determination to succeed, and the work is half done already.
