I was working with a man in his 80's this week. He is profoundly weak. As I explained to him the sequence of events our bodies go through, both gaining strength or weakening. His eyes lit up as a realization hit him.
He told me he had a routine for years and years. Stretching, push ups, core work, everyday until recently. It is a lot harder to gain strength than it is to lose it. It's amazing how quickly our bodies weaken with rest. He said to me; "My mistake was in stopping."
This is true in all areas of life. If you are someone who wants to grow and change for the better through life, it takes action. As I've heard throughout my life from different, wise people, the job, the marriage, the fitness, etc. . . is not going to jump up and knock on your door.
I write down my goals, visualize the completing the task and take at least one step toward my dream each day. I figure the days are going to go by anyway, I may as well end up somewhere better than worse.
Fantasizing the freedom to change for the better, one day at a time.
