Establish A Board Of Champions

a. Every quarter or so, put up a dozen of these advisers friends, family, business associates whose opinions and judgment you value into a room and allow them to critique every aspect of your business. For the cost of a nice lunch this board of advisors can give you a different look at yourself.
b. Dont be thin skinned , they may be hard on you or your product, but thats the purpose. They may see problems that you dont. Grow from the experience.
