Serving out a two-month notice period while already mentally somewhere else

Six weeks left. The work is still real and my name is still on the commits, and I keep catching myself doing about 60% and calling it enough.

Two things that have helped more than trying to force motivation:

I picked two things I actually want to hand over properly and consciously stopped caring about the rest. Trying to leave everything perfect was making me do all of it badly.

And I've been writing the docs I avoided for a year. Apparently I do my best documentation when I'm leaving, which says something depressing about how I work under normal conditions.

Anyone got a better system for a long notice? Two months is a strange amount of time to be a ghost.
