I have periods like this Tom. So you’re not alone.
Sometimes we need time away.
What I find is that when I feel I should be doing something, even if I don’t really fancy it, I go into the workshop and put a piece of something on the lathe and just start doing stuff. Anything really. Maybe make a key ring, spinning tops or a tool handle. Before I know it a few hours have passed and I’m back in the zone.
Also I bet you’ve got a blank in there somewhere that’s already cut. Just use that and make something nice. Enjoy yourself.
Cheers
Ash
