At the day job
In my home office.
gr8noise suggested the difference was down to "passion." In that "the day job is for pay and the home office is a whirlwind of activity that you would do for free."
I think he has a point. I also think it has to do with different mind sets. At the day job I need to be the analytical, clear thinking guy in control.
The office space at home is where I let the creative side have full reign. Here my mind is in a more chaotic state and I often have multiple creative projects going on at once.
Well that's my excuse and I'm sticking to it.
