I'm going to start with a disclaimer, this does not work for everyone but it did work for me. I made a lot of changes almost faster than my little brain could process. I got a job that allows me lots of free time, got out of my lease in an expensive shithole house, and bought a van that I upfitted to be a comfortable camper. I'd bum off my parents for a place near work when I was needed, and use my free time taking camping/road trips. Combine this with some plant-based inspiration and before I knew it I was effectively on top of the world. I've since sold the van and live a pretty lame life again, but I am moving soon. Essentially if whatever you're doing now isnt working, change it! You're not obligated to just waste your life, as far as I'm concerned we only get one.

TLDR: Downsize, do exactly what you want to do within your means, don't be afraid of change, always stay busy and give yourself something to look forward to!

Imma toot my own horn, I've lived this philosophy for a couple of years now. It's so peaceful and I've found success with it too. When you put desperation aside you just naturally succeed.
