It's amazing to me how I can – sometimes – make more progress in 3 hours than in 3 days. I've spent a large part of this week slogging through some revisions. I had lot of trouble staying motivated and focused, but I kept pushing at it day after day because I wanted it to be done. Today I whizzed through the rest of the task and was done with it just after 2 pm.
And man, does that feel good.
