The things you do on your own are what matter, not the things that you’re forced to do. When you can learn to love doing the things that you would be forced to do, that’s where you strike the perfect balance of happiness and productivity.
You must develop and practice self-discipline to change your life. It’s difficult and if you don’t keep up with it, you slide backward and lose momentum and punctuality, but it’s the most rewarding thing you’ll probably ever do.
