Personally, I'm working two days a week to pay the bills, and spending the rest of the time working on my startup. I find working only two days a week, it's a lot easier to keep perspective on my real goals (start my own company) versus short term goals from the "real job" (fix a bug, get a feature out the door, etc).
My situation is that I used to be involved in startups, but I'm now all corporate.
If I had to choose from the list, then both "interested in working for a startup in the future" and "just like reading" are fairly appropriate, but the latter option paints me as rather more of a dillettante than is actually true.
I'm doing 20 hours a week as a W2 employee through a consulting firm for an old project that I used to work full time on.
I do about 10-15 hours of random freelance work a week.
I publish my own iOS apps which I work on as time allows, but generally I get one out every 2-3 months.
I also have a few side projects I'm working on.
(This is in the interests of fairness and not out of any personal bias.)
I'm doing 2 or 3 days a week freelance/contract work to support working on the startup the rest of the time.
The aim being that when we turn on payment in the next few weeks I'll be able to scale back the freelance work to spend 100% of time on the startup.
There's actually quite a few recruitment startups around this area, maybe we should organize a dinner for us all or something.
I just @ replied you.
Although I'll admit that this is a dream of mine. Someday make enough money to go back to school as a "gentleman scholar"...
