There's power in a hunch, but the power comes not just from believing any thing you think, but in building your "hunch" muscles and learning to trust them.
In the book Hunch, Bernadette takes us through this journey by introducing (or re-introducing) us to people who have honed their skills and have learned to build better businesses and projects based on their hunches.
If you're looking to create a project and everything seems to be aligned but yet you have this feeling that is keeping you from moving forward, then it would help you to pick up this book and dissect what may be the cause of your hesitation.
This another well written and researched book by Bernadette. I highly recommend it.
