Earlier quoted context omitted.
40 manhours is HUGE if you have a day job.
the average american watches 4 hours of tv a day. if you're average in that respect, you could churn out one of these projects every week and a half.
Also, I can't imagine how anyone with a full-time day job (40 hours, nothing spectacular) can even manage 4 hours of free time. I don't think I have 4 hours a day.
