Now, should this new opinion have an impact on your strategy at all? Your call; you can't outsource innovation to the people you’re trying to help.
"Remember: when people tell you something’s wrong or doesn’t work for them, they are almost always right. When they tell you exactly what they think is wrong and how to fix it, they are almost always wrong."
Take your chances. Materialize the vision. It might fail, it’s true, but all progress hinges on your willingness to bear the risk.
Just don’t hurt anybody and try not to get hurt.
