I'm sort of right there with you but not quite. I quit my shit job. I don't really care about money, but I feel the need to do something useful for people and have something to show(read: live indoors and eat) for my time. I don't feel comfortable initiating things in general, so I haven't made any posts yet, but I'm happy to be a part of the community. There are plenty of negative things going on in the steemit community, but it's just as easy to find the positive if you look. I'm still trying to get a feel for it, but I'm glad it's had such a positive effect on you.
welcome to steem! I would say you can spend a lot more time studying the https://steemit.com/welcome page, and in the comments for your initial experience here, and then when you start to actually write articles\blogs, you will already be a lot better off and ready to create your own thoughtful content
