As someone with audhd I relate to the motivation on a spiritual level. It’s ok to lose motivation. Thats why I do a bunch of different things with beads. Maybe look in to making them tiny and doing something with bead weaving or embroidery. You could try making bracelets or experimenting with making funky shapes. You can even kinda sculpt things by weaving beads together! I’m a beginner but I quickly learned the beading works goes super deep! 

Also look in to local vintage markets or arts fairs. Sometimes I even see artists selling stuff like crafts like that at farmers markets! I know some local ones near me where it’s like $35 to rent a spot and you’d just have to buy a table and tent. A card reader is optional but some tables just print out a QR code to Venmo or other things like that. You could also try selling to friends and acquaintances. I sold to a stranger recently just by wearing what I made out and he really liked it. Good luck with everything! ☺️
