Honestly, I'm just spoiled. This is only working 40 hours a week - it's just the demands of the job vary tremendously and are not predictable. I may work 60 hours one week, then have time off for later. I always want everything done, and well, super early on rather than just pacing myself.

It's more the stress level, and the stress I put on myself. I can work any time - in other jobs you may just work when you're at work or not be so pressed that if you had down time, read a newspaper, or smoked in the alcove that you'd be backed up. But...my god, I'm lucky I know. It's more how it feels than how much time it really takes.
