How do I unplug?

I was taking a mental break from work while eating lunch and read a couple blogs that I've found inspiring. A few minutes ago I read Self Made Chick's post "5 Things I had to Unlearn to Become Self Made." Here's an excerpt that really spoke to me:

"Making the shift from the corporate world to working for myself was a lot like unplugging from the Matrix. There is a completely different world all around us, but we are unable to truly understand it unless we live it. This, I believe, is why I had been unsuccessful for years trying to start my own businesses part time while still working full-time for someone else. Self sufficiency is a completely different mindset.... If you don’t have the energy or time for new things to come into your life, they won’t."

Why is it when someone points something like this out, I think, "YES! I know!" How do you make the leap from doing what you want with every moment of the day instead of what someone else wants you to? Let me rephrase that, how do I make the leap from doing what I want with ever moment of the day instead of what someone else wants me to? I don't know, but I want to find out. I'm totally open to insights here.
