Your power resides in your strengths.
Your power either energizes action or it rests inactive.
Your power is the sum total of your talents, the opportunities you've had to put those talents to work at tasks, your knowledge related to those talents, and the time you've taken to practice and develop work-skills based on those talents.
Your power is put to good use when you employ your strengths through good habits.
Good habits, naturally, take you toward your long-term goals and vision.
And, of course, if you do not have long-term goals and vision then your power rests inactive and your strengths do not realize their potential.
