First, let me say that I love my job and how I make my living. With that said, video production IS NOT my life. There are other things I enjoy and look forward to a lot more, including time with my family. I live well within my means, drive normal cars that are paid for, and live in a modest house that is paid for.
So for me, with my gear package and at market rates, 12 days per month / 12 months per year (the 12/12 plan as I call it) is my target. Some years are 130 shoot days, some are 150 shoot days. I can get by on far less than this, but I've been blessed so far in my business to "hit my marks" over the past 12 years since formalizing this plan.
If I am shooting three days a week and spending another day handling invoicing, checking gear, handling logistics, paying bills and vendors, then thats four days of "working" a week. Why in hell would you want to work more than that?????
Now, if I am working without my gear, or working on some bargain basement discount shoot, that number would shift.
