I'm the better part of 40 and I still don't know what I want to do. I've drifted through life from one thing to another with no direction, focus, or interest.

I'm the better part of 40 and I still don't know what I want to do. I've drifted through life from one thing to another with no direction, focus, or interest. Like you I've tried many things (though mine are probably more extreme at a guess) but after a while I lose interest. Depression has dogged me all my life like a bed-fellow, and that my friend sounds a lot like what you are experiencing. My depression stemmed from the seeming pointlessness of life. Ive come to realise it is pointless there's no grand design, no reason, no meaning; it just is. So I just am. Nearly 40 years and I'm pretty happy with this; nice house, beautiful wife, two wonderful children, a job where I make a difference (to people's lives not some boss's bottom line) even if I don't really like a lot of the baggage that comes with it. Rather than spending all day reading Reddit try some books. Buddhist philosophy (zen), daoist philosophy (Dao De jing, Zhuangzi), stoic philosophy (quite popular these days). Maybe it helps and maybe it doesn't.
