I liked this quote - "I think the essential way to do anything great, you have to have some incremental development philosophy because you're just going to be wrong with your grand design that you don't iterate on."
You're not really doing something very revolutionary if you're not running into some dead ends.
You don't have a clear idea of what it's going to be when you start, you have an inkling and then, each step tells you what the next step is but you don't know what the next step is until you've gotten to a certain point.
We thought we were making an exquisite product, the best possible thing at the time but then, we figured, in a few years we'd make something a lot better, completely different. We didn't realize the architecture we were putting in place could last five years, let alone 10, 20, 30 years.
I think the essential way to do anything great, you have to have some incremental development philosophy because you're just going to be wrong with your grand design that you don't iterate on.
