I didn't think of any revolutionary ideas, or come close to a successful business like lots of people, but... My first job was answering the phone for an early dial-up ISP, and since I claimed to be able to program, one of the two founders (I forget if it was the tech guy or the business guy) suggested that a good project would be some sort of electronic auction/want ad system. I was like, hm, ok, I have no idea how to do that, maybe I will read about electronic auction systems at the university library. Where I got overwhelmed and didn't do anything further. But in retrospect many years later, they asked me to invent eBay the same year eBay was founded and the internet as we know it was taking off. It's hard to shake the sense that at that moment in history I could conceivably have done it if I simply had no sense of my limits and infinite energy like many successful people. Instead I proved I wasn't cut out for customer service and they laid me off before the company was acquired.
