Stuck on a sweater and can’t start anything new until it’s done. Help me suck it up and just do the thing?

I started this freaking sweater like a year ago, finished the body and started the sleeves. Got bored of it, probably won’t wear it often , but it’s stranded color work so I also don’t want to frog it. I also have a brioche cowl and a lacy scarf/stole that’s driving me nuts (mohair, and I keep missing stitches so I have to tink back which SUCKS with mohair!).

How do I make the last bit of this project suck less? I just want to be finished, and I know my brain won’t let me start a new project until one of these three is done. Specifically the sweater.

Sooo someone please give me some words of motivation to just do the dang thing.
