I dunno if this is exactly the same application but I do something like this for basically every aspect of my life. Since I work from home and quarantine it’s been more important to keep a regimented system that lets me see clearly what I could be doing more efficiently!!
Right now I’m on a tight schedule with a graphic novel deadline that, honestly, I kinda goofed up early on in the project because I was letting other things take priority that I shouldn’t have. I’m currently penciling and inking 12 pages a week which now takes me from Monday to Wednesday and then I take the rest of the week and some of Saturday to work on my side projects that I’m hoping to send off after I hit this deadline.
Everyday I write out exactly what I need to do without any room for vagueness (instead of ‘work on comic’ my list now says ‘pencil/ink next four pages’) and segment my day into three hour chunks that I’ve kind of turned into a little game with myself to see how efficiently I can do a chunk of work so that the load doesn’t bleed into the next chunk.
I keep a log of how long it takes me to do everything and then at the end of the day I make a List of Things to Improve that includes from how quickly I get to lettering the comic to drinking more water and running more miles. And that list ends up also being part of the to-do list the next day and I cross those off if I’ve achieved them.
Part of this for me also involves not using the internet for more than an hour a day and it turns out I was not nearly as focused on my work as I thought I was before I started this!!
I was working everyday through the weekends trying to get this stuff done in time and now I do it all over the course of three days between 9am and 5pm so I have lots of spare time for other projects.
