So with crafts like that, there's an area where you're starting out learning that it would be nice to have time reset daily.

Getting into woodworking, I used up a lot of lumber practicing making joints. If I could have my practice boards back, the ones I learned how to make dovetails and box joints and mortises and tenons etc., it'd be kinda nice. Also, saw blades would never get dull. Supplies wouldn't go bad or dry out.

Learning to speak a language, or play an instrument, as long as you had easy access to the instrument, would work fairly normally.

Some people do things for the accomplishment and acchievement, but others do them for the love of the process.

I'm with you though: If I never made any progress, I'd either have to figure out how to rewire my brain, or I'd go insane.
