A quote from Bruce Lee

I would like to add a quote from Bruce Lee. This is a quote that you can find on one of those posters. It’s useful because all these insights you know, you easily forget them and lose them out of mind. Solution: apply immediately and transform them into concrete change. Here it is:

“Knowing is not enough,

you must apply.

Willing is not enough,

you must do.”

Ps: I just saw on a website that it is also a quote by Goethe. Maybe Lee just took it from Goethe (he takes freely from all). Or maybe coincidentaly they thought of the same thing?
