Website ideas

How do you guys find ideas on what website to create? I'd like to make money off a website, but it seems I simply can't find an idea of a website. The fields I'm really into all seem to be satured: fitness, tv shows.

Try different things such as PPD or PPI. Find new games that are hot and set up a website for those
then create videos on yt to get traffic. Just choose something, and START IT!
