You can (probably) do that right now. You just have to give up on the idea of advancing any aspect of your life to do it. Related quote from the movie Fight Club: "it's only after you've lost everything, that you're free to do anything." I think about that line a lot, because it has both positive and negative implications.
Ya. Well that's why I added the 'probably'. Unfortunately sometimes maintaining a zero sum can be all the work of improvement without any of the benefit. Feels like furiously firing rocket engines just a hover in place. I've been there; still am in some regards. Best of luck to you.
