Well, I think that the most important question you need to as yourself is why do you want to be free from the cube? Unfortunately, happiness might not be enough of a motive. Getting free would talk you plenty of work, giving up some fun things you do right now for the possibility of a great future. The problem here is if you WHY is not strong enough, it will be easy to give up and not complete the small actions you need to complete daily to stick to your goal. Once you have your why strong enough ( usually, this means that it's for a greater cause than just benefiting yourself) then you can focus on the strategy to get you there.
