> A book recommended by YC's Aaron Epstein is The Mom Test[0]. The first 50-60% of the book is dedicated to how to discover problems with end clients/users that are worth tackling.

I can't recommend this book enough. It lists every single mistake I ever made and every lesson I learned in doing so.

The only problem is that I discovered the book after making those mistakes and learning all those lessons.

Of course, following the advice in the book won't guarantee a successful business. But I'm 99% sure that NOT following it is a sure-fire recipe for failure.
