It is for you.
It is for the person you are becoming when you are not giving in to your lower level desires.
It is for the healthy body and the strong mind and the body of discipline you build for yourself.
It’s the strength of character you demonstrate to yourself.
It is the uncanny willingness to show up when you can skip a day or two and no one will know.
You will know. That is why you must show up. Nothing else matters.
