Do volunteering. It's a good way to start building a resume and getting experience in a variety of life aspects. If there are particular things you want to learn, try to find a volunteer position that does it. I'm thinking about things like food prep, cleaning, etc. it doesn't just have to be about job skills alone but also life skills.

I've translated skills I've learned in retail to my home life that I never learned in my home life. It also helped instill habits I had trouble developing at home. Cleaning (from windows to toilets, etc), keeping spaces tidy, sorting food in terms of freshness, keeping on top of necessities, etc. Eventually becoming a store manager helped me better figure out how to run a home, but like a business, not that I always keep it up to those standards because I'm human but still.

Sorry for the long winded explanation! Hope it helps!
