Currently I'm in the complete opposite modus operandi. I don't do a lick of side-project work during the week, and on weekends I take a modafinil(wakefullness promoting medication) and stay up nights on end to crack out as much as I can.
I get an INSANE amount done on the weekends that I have the energy to pull this off, but it's horrible for my health. The rest of the week I have anxiety about the coming weekend, and it completely throws of my circadian rhythm. Not to mention that I'm only able to pull this off perhaps once or twice a month.
I'll definitely be changing my work schedule to be more in-line with a daily habit. Being able to look back and see a lot of consistent work being done sounds way preferable to being able to look back at a few weekends of consistent insanity.
