A bility comes from action. To become skilled at doing something, you must first begin to do it, and then continue doing it until you have mastered it.
Powerful abilities come from patient, focused practice.
Each day spent in diligent, directed effort strengthens your ability to make that effort. The more you practice anything, the more advantage you earn for yourself in doing it. As such, each and every moment spent in focused action is a reward unto itself, no matter what the immediate outcome or result. The assiduous efforts you make will indeed pay off. They cannot fail to do so.
