This book is going to help you a lot with establishing whether you really can do it or maybe only have been fooling yourself: Nail It then Scale It: The Entrepreneur's Guide to Creating and Managing Breakthrough Innovation, Nathan Furr & Paul Ahlstrom It's basically a unique primer on the exact topic you've been struggling with.
