The benefits of knowledge can only be realized in practice.

If we have a correct theory but merely prate about it, pigeonhole it and do not put it into practice, then that theory, however good, is of no significance.

Science is the captain, and practice the soldiers.

Partial knowledge is more triumphant than complete knowledge; it takes things to be simpler than they are, and so makes its theory more popular and convincing.

Practice is absolutely necessary. You may sit down and listen to me by the hour every day, but if you do not practice, you will not get one step further. It all depends on practice.

I've leaned on God for so long. "Hey, God, you just gave me this gift, and I'm just going to go out there and sing." But I'm realizing how much larger and how expansive my gift becomes when I actually pay attention to it and try to practice and try to perfect it.
