From Paul Graham’s “Frighteningly Ambitious Startup Ideas”. As usual, it is a great essay where you could get inspired.
“Empirically, the way to do really big things seems to be to start with deceptively small things. Want to make the universal web site? Start by building a site for Harvard undergrads to stalk one another.
Neither Bill Gates nor Mark Zuckerberg knew at first how big their companies were going to get. **All they knew was that they were onto something.
Maybe it’s a bad idea to have really big ambitions initially, because the bigger your ambition, the longer it’s going to take, and the further you project into the future, the more likely you’ll get it wrong.
You’ll be better off if you operate like Columbus and just head in a general westerly direction. Don’t try to construct the future like a building, because your current blueprint is almost certainly mistaken. Start with something you know works, and when you expand, expand westward.”
