There are a few quotes I've run into over the years that I think are particularly notable / insightful. The first candidates for my top 10 are accumulated here:
"The future is here. It's just not evenly distributed yet."
- William Gibson
"Men want every woman to fulfill their one desire, and women want one man to fulfill their every desire."
"Faith is suspending doubt long enough to experience the truth."
"Lots of people have lots of brilliant ideas all the time -- it's the ones that actually realize those ideas (their own and others') that make the difference."
