started 3 businesses, and seen other ENTPs be very successful starting their own
but I've learned that the best ideas start with observation, not inspiration, even for ENTPs
what I mean by this, is that you have to put the Ne to work to find the need, this is very different than surveying or doing market research, which almost never produces a great business, but rather using our Ne to observe something wrong that can be fixed with a completely new idea no conventional thinking numb nut would ever come up with
Steve Jobs, for example, probably wouldn't have come up with the Mac if it weren't for his frustration with command line interfaces
I find it useful to stop my mind and just think about new ideas that could be products, but I need to do light exercise, especially walking, to do this, sitting at the computer is way too distracting
