I won't take time to repeat all the obvious benefits of physical exercise but will only underscore the well-attested fact that a program of regular exercise increases one's efficiency in every facet of life, including the depth and restfulness of sleep. And the time taken can be minimal; just a few minutes of calisthenics and running in place in one's room or jogging around the yard or block is often sufficient. Exercising doesn't take time. It saves time. Still, few consistently do it.

Unless you’re continually improving your skills, you’re quickly becoming irrelevant.

The way we see the problem is the problem.

During the first few minutes in lift-off, the astronauts were strictly controlled and were powerfully buffeted by the forces of nature struggling to keep them on earth. This is somewhat comparable to the pull of the flesh when our alarm goes off early in the morning. Unless we put "mind over mattress" and carry out the resolves made the night before, we will experience our first defeat that day. Not sufficient to finish. Mission aborted.

The fire inside people is like a match; the way to ignite that flame is initially through friction, then other matches are lit through warmth.

What is important to another person must be as important to you as the other person is to you

The key is not to prioritize what's on your schedule, but to schedule your priorities.
