Ask HN: Are you put off building something because it already exists?

Big market, check. Validated demand, check. Product or service exists, uh-oh. I set out to build a reverse address book. Instead of updating your address book with changes from everyone else, you update your own details and it pushes to everyone else. Turns out someone beat me to it and my inspiration evaporated. Zoom is a recent and great example of competing in a crowded market and winning. For you builders/founders out there, are you on a never ending quest to find something new/unique or do you prefer another quality in your idea to start a project?
