Physically we can be more active. If you were to sit up in your chair and take a deep breath and clap your hands vigorously, your energy level would rise dramatically. This stimulates the body and thus effects the brain as well. Coffee is a crutch, not a solution. Spiritually we could teach others what we know.
Teaching is like hammering a nail.
This also helps generate motivation. The stronger you want your structure to be, the more you must teach. Whenever you want optimum results in any kind of achievement, you need to get into a specific kind of state. A state of mind is simply an emotion we experience at any given time . For example, we can be in a depressed state or an energized state.
