It wasn't easy, it was hard. Painful and scary and exciting and anxiety inducing and hopeful. I started by forcing myself to do it but the more and more I practiced the easier it became to search for inspiration within myself - like digging a well. At first it was sand and dust and rock; nothing alive. But the deeper I dug I found clay and mud and water and eventually I _learned_ how to find that spring of life within myself, and I could use that water to irrigate the fields and find life and mystery and inspiration in the world around me.
I don't know if art is what makes us human, but I found that art at least showed me what makes me feel alive.
Here's a song I thought of while writing this: https://www.youtube.com/watch?v=1FeD16vu_qQ
There are a lot of possible causes as to why you may feel a lack of joy. The good news is that the vast majority of those causes are fixable.
The analytical part of the brain is not the only one.. that said, I'm neuroscientist, just a dude with a strange upbringing.
Pothead here, also probably autistic, also dealt with a lot of family trauma, also positioned to retire soon.
If you're smoking weed to feel a "cosmic connection" (which is reasonable IMO), you might want to look into trying more powerful psychedelics.
There's a lot of interesting research going on with mushrooms for depression: https://www.webmd.com/depression/news/20210415/study-magic-m...
I'm planning on waiting until I'm fully out of tech, then tripping balls and working on fixing myself instead of fixing code.
Given that you suspect that you are neurodivergent(you mentioned autism), please talk to a professional. Maybe figuring out exactly what makes you tick is what you need - or maybe there's something that's preventing you from feeling 'joy' (anhedonia is a classic depression sign).
Don't wait until retirement. You can certainly afford talking to a therapist (from a monetary perspective at least, time may be another matter). But just do it.
I think that 'joy' is a target that can't be reached. No matter how wonderful one's life become, we'll adapt. Joy is fleeting (but you should still experience some occasionally). Not hating having to wake up is a good first goal though. I'm also working on that part.
