I don't do all the extra stuff with time-tracking that the full method goes into; I just sit for a bit and make a little list of a few Things I'd Like To Do Today, with 6-8 checkboxes (for the total list, not each task) next to them, each representing a 25-minute block of work. Then I take the timer sitting on my desk (it's shaped like a cute ladybug, and has had everything after the 25 minute mark painted over, whimsey is important), wind it up, and start working on one of those things. When it dings, I stop for a break. Get up and stretch, go to the bathroom, get more water. Maybe get right back to working on what I was doing, if it needs more work and I'm excited about it; maybe work on one of the other things because I need a break from that thing, maybe just fuck off and take a longer break for lunch/slacking off/whatever.
There are ways to do this entirely in software, but I find I like the physicality of winding up the timer and having it sitting there on my desk ticking away.
And all that said, (a) I haven't been doing this lately, (b) I've procrastinated on my taxes until the last minute. Which is pretty much today I guess, ugh.
