Someone on the forums once said that people seem to think that changing from a theist to an atheist or agnostic seem to think they deserve a medal. And I responded that yeah, it takes something more that ordinary to break away from that brainwashing, that conditioning, and explore reality with an open mind. More or less anyways. It takes something else to look at what someone has always told you was on way, and then figure out that there's a possibility for it to be another way. You were raised by people who said you had to be this, do this, act this way. And at certain points in your life you realized that this wasn't the only way, that maybe it wasn't even the right way. That's a hell of a big deal. I applaud you for that, I really do.
Zero motivation, zero ideas, and completely drained? sounds like me, at both the end of my time at the university and at the end of my time with the army. Finding that thing that fits you as a career, as far as ability, aptitude, and demand? There may be no such thing. Religion might tell you that any drawbacks are intentional, part and parcel of some grand scheme. I don't think so. If there's something you want, you have to put up with what it takes to get there. Maybe more school, maybe less pay, maybe any number of other things. Don't expect perfection. Only you can determine whether you can balance what you want with what you need... and what is right.
Most people don't settle for what they want. They settle for what they can get. Ideals are fine and all. They mean something to me. But they aren't shared by everybody. And that's the kicker.
