I don't see the point in finishing things for the sake of finishing it if you aren't into it anymore, it's literally a waste of time and effort you could spend doing other things XD
I get where people are coming from as a habit building thing or whatever but finishing what you started regardless of how you feel about it only works for a small number of things XD
Now I try to "wrap things up" and call it done xD Even though it's not what I initially planned haha. I just pretend it's finished :P
It's done if you decide it's done right 😜
