You do what you want. People make room in their lives for the things more important to them. They stay up later, move around the free time that is always present. You make choices to spend the next five minutes on something important or something frivilous, but all of it is a choice.
Take responsibility for what you truly want to do and live up to that. Write it down and stay true to that.
We all pick and sort our course every day. Stop with the excuses.
