The Importance of Discipline

I was just doing so many shortcut methods to make us both happy. And in the end, it just sort of crumbled away. I am trying to become more disciplined and learning that it's hard. There's times that you don't want to work out four days a week. Just want to sleep in. But then if you do that, you take a look at yourselves like, what did I do? Nothing. It doesn't feel good because I feel like I took a shortcut.
