Energy is always required to provide lift over opposing forces

Energy is always required to provide lift over opposing forces. These same laws apply in our personal lives. Whenever an undertaking is begun, both the energy and the will to endure are essential. The winner of a five-kilometer race is declared at the end of five kilometers, not at one or two. If you board a bus to Boston, you don’t get off at Burlington. If you want to gain an education, you don’t drop out along the way—just as you don’t pay to dine at an elegant restaurant only to walk away after sampling the salad.

Whatever your work may be, endure at the beginning, endure through opposing forces along the way, and endure to the end. Any job must be completed before you can enjoy the result for which you are working.
Endure and Be Lifted Up, Russell M. Nelson, April 1997 General Conference
