Very well put, Luke. I just have to add my favorite text on self-reliance:

"Everyone in the world is governed by self-interest. People naturally think first of themselves and their agendas. An occasional affectionate or helpful gesture from people you know tends to cloud this reality and make you expect more of this support—until you are disappointed, again and again. You are more alone than you imagine. This should not be a source of fear but of freedom. When you prove to yourself that you can get things on your own, then you experience a sense of liberation. You are no longer waiting for people to do this or that for you (a frustrating and infuriating experience). You have confidence that you can manage any adverse situation on your own.

Think of it this way: Dependancy is a habbit that is so easy to acquire. We live in a culture that offers you all kinds of crutches. Experts to turn to, drugs to cure any psychological unease, mild pleasures to help pass or kill time, jobs to keep you just above water, it is hard to resist. But once you give in, it is like a prison you enter that you cannot ever leave. You continually look outward for help and this severly limits your options and manoeuverability. When the time comes, as it inevitably does, when you must make an important decision, you have nothing inside of yourself to depend on." -Robert Greene
