I'm a learning 3d artist, and this work is the first I've ever had that is indoors and not physically involved. I've been at it for just over a year now. Some days, especially when I hit or am near a milestone in a project, I can easily work eight hours or more, no sweat. Sometimes that ccrazy energy last for several highly productive days. But a lot of days, especially when the work is tedious or it's a long way to the next milestone, I am really only good for like 4-6 hours of legit work, and the remainder of an 8 hour day I am still productive but like, only 25%. In those remaining hours I'm no good for decision making, hard figuring, organizing -- just mindless work and I'm prone to distractions. (That's when you see me here) Is this normal? At your day job as a programmer or any type of computer work, do you routinely hammer out eight hours of solid work five days a week? Reason I ask is because the ho-hum days really irk me. Make me feel like a lazy bum. Besides coffee and exercise breaks, are there any tips/tricks to keep the brain focused those extra hours? Or is it really too much to ask? I suppose a big part of the difficulty is the solitude, little feedback, and so on. Probably at a day job you have meetings and people stopping by, that sort of thing helps.
