I purchased a book called The Mom Test, based on a recommendation from another founder, Jon. He's building his own business around a platform for community building. He is also doing a great job inspiring others with his daily updates.
I'd recommend this book to anyone trying to push past the idea stage or even business owners looking to improve their product. The book teaches you how to have constructive conversations with customers so that you can get to know their true problems and needs.
This is an incredible ability to master. It can help you validate an idea more quickly and also prevent you from being lead astray by well-intentioned compliments.
It's a short read but offers incredible insights. I've already started using some of the tactics in my conversations and these have been some of the most helpful meetings to date for our business.
If you'd like to start a business someday or even just hack together a project, check it out.
