"People who wants ur Product may tell something bad about your product or about yourself.
People who understand your product may tell some concerns about your product.
People who did something like your product may tell something different about your product idea.
People who neglect your product may not tell anything about your product.
Bottom line is : People are people. they will tell anything that they usually understand, dont understand or trying to understand. Listen and understand to what is productive.. Listen and let go to what is useless. Prepare a filtering system in your brain, train that everyday , and keep that updating continuously..
