Every great accomplishment began with the germ of an idea in the mind of a great person, then was shaped for practical usefulness and finally transformed into reality. Make your mind a fertile ground for ideas through constant study and learning, and condition through constant practice to discipline yourself to follow through on your good ideas. The most brilliant concept in the world is only a dream unless you take action. Even a mediocre idea that is put into practice is far more valuable than a flash of genius that languishes in a fallow, undisciplined mind.
