I like this approach. It's kind of like the 'No more zero days' mentality that's taught to people who are juuuuuuuuuust starting to come out of paralyzing depression, but with a little extra oomph.
the first day, the goal might be "write out a list of manageable goals". There you go, you did the thing. I have to do this to myself. my list of things for the day: get bloodwork done practice music for orchestra concert on the weekend edit my paper for 1 hour do laundry make my bed practice the viola da gamba they're all pretty manageable, and have an end point goal, a stop point. I'm not just nebulously editing my paper, i'm working on it for an hour. I'm not just practicing my bass music, I'm running through the stuff for the concert. the only nebulous one is the gamba practice, and that's because it's "for fun".

this is a viola da gamba It's like a cello and a guitar had sex. in fact, it's one of the ancestors of the modern guitar, and the modern double bass.
naw, that's this guy: Joel Quarrington is... a gift.
