Ima address this just cause the devil doesn't need any advocates, he's doing fine. Did you get a hundred bucks worth of joy out of your m2 and the fancy labels you made and all the learning how to do it and what to do before you lost interest? I believe so hard that joy is a fine variable when I'm considering value for money.
I've got a tongue drum I bought from Russia that I fretted over just randomly dropping like eight hundred bucks on with shipping factored in when I didn't even know how to play the damn thing when I bought it. But I've absolutely gotten eight hundred bucks worth of joy out of it when I consider all the hours I've spent playing it since I got it, and the longer I have it, the better that value ratio is because I keep getting joy out of it. But if I lost interest in it tomorrow and never touched it again, it still wouldn't be a waste because all the joy-hours I DID get add up to a good return on investment overall.
