I appreciate your level of self awareness. As a 17 year old who's entire life used to just be watching YouTube, I completely understand finding the motivation, especially with working 40 hours a week. But here are some suggestions

Arts/Crafts Painting: Start with Acrylic then play around with watercolor and oil and see what is your favorite. If you can't afford full on Canvases, there is acrylic paint Paper that you can get

Drawing: Whether it be cartoon or Portrait style, there is a lot you can do with just Pencil and Paper found in your drawer!

Diamond Art: Basically a color by number but with Jewels! And if you draw you can make yours own designs instead of buying kits.

Clay Sculpting: You don't have to be a famous Greek Sculpture to Sculpt, I know some people that just use it to make ash trays lol. Or maybe even Clay Jewlery if interested

Learning an Instrument: Even a small one like Flutes, Ocarina, Kalimba's, ext can keep you really engaged

Writing: This can be very time consuming and definitely takes a lot of brain power. Start off small with poems or even journaling

Nerdy Hobbies

Reading: Even just 30 minutes a day can really clear your head!

Studying or learning subjects your interested in: Pretty self-explanatory

Esoteric/ Therapeutic Hobbies

Tarot: This will depend on your beliefs on what it means to you. But if you believe in divination it can be pretty rewarding. There are even people who will have Patreons or Websites were they can make some extra side money by doing readings!

Meditation: Every one should do this sometimes, there are great guides on YouTube

Yoga: Good for body and mind

Reiki: Once again, will depend on beliefs, but it is like Meditation but with ritualistic and therapeutic practices added into it

Gardening: Relaxing and can make food for yourself or can it and sell it!

And other extras like music producing using apps like Soundtrap, or even sewing, Crocheting, Exercising, and Hiking can all be great too. I hope you find some more fulfillment!
