Congrats on making it to the halfway point! I'm totally with you on feeling a bit surprised at sticking to it this long... I'm a couple of days behind you, and you're quite right, sometimes it feels like an accomplishment, and sometimes rather pointless.
But it also feels like certain new pathways are forming in my brain... and I'd like to think this will stand us in good stead, in the long run!
I don't have the experience of new pathways forming. Maybe because I'm not focussed on one thing. I'm not trying to create a habit either so I'm left wondering why I'm doing this. The only reason I keep coming back to is using up stuff but then I could always just give it all away or bin it so that's not much of a reason either. It's all a bit puzzling. 😕
