You have noticed! Good job.
Many people go right through life without questioning anything. They work hard a school, get good grades, get a job, progress, get married, have kids, go on foreign holidays, work until retirement and then... oh crap... what was it all about?
Maybe check out Alan Watts' talk on "Life Is Not A Journey". I found that fascinating (especially given the recent post on here about art, too)...
You are correct. NOBODY knows what they're doing. I've found that the ones who claim they do are the biggest liars.
Society, and "normal" are fascinating.... as lili over on bearblog put it: "The rules of society are arbitrary, something that becomes clear when you travel enough." It's so true. Go see a large number of 'normals' and you suddenly question the one _you_ were brought up in.
This questioning makes life harder for sure, but for me it feeds my soul. I don't know any other way to live.
I don't know what point I'm making really (because, like everyone else, I have no idea what I'm doing)... maybe I just want to let you know you've been seen and heard and no, you're not crazy!
