I'm a self-taught web dev in my mid twenties that want to start a SaaS business. I've been thinking about what product to build, but IMO every time it's all coming down to find a need and then build a solution. The thing that eludes me is how I find those needs and where to look for them? What do I miss? Is my approach wrong?

I can't wait to hear your opinions and stories from your own experience.

Thanks a lot!
