do you ever start planning what you're going to code next while you're falling asleep, or when you take a toilet break or walk somewhere? or when you go to a meeting and sketch out that new module or whatever? reminds me of a hemingway hack. it's hard to sit down to my computer with no specific goal in mind, or just the high level "i have to finish this story" in mind. it's easy to slide into other things. but if i've been visualizing the code i want to write, or if i have a sketch of the data or algorithm, then i don't waste time.
