You talk of tiredness as a matter of importance. It is to you and many other people on this planet. How can one go about their daily chores when they are feeling tired, how can they best be themselves, when this tiredness controls their bodies.
Take a look at yourself for a start, and cast out of your life anything you are overdoing, that is unneeded. The way to complete any task with the least effort, is to work at a steady pace. Does a tree and it’s branches and leaves grow overnight, every spring. No it takes weeks and months to grow, to its full size and elegance, moving at a steady and even pace of growth.
