Been listening to the book "The Start up of You", by Reid Hoffman the co-founder of LinkedIn.
It is a good listen, or a good read.
There was comment he made that made grab a pen and paper. Of course I was driving so I had to wait until I stopped, re-wind and then make the notes.
The quote was 'when the naysayers get loud, turn up the volume'. When you are surrounded by negative people who can't say anything good about the idea, stay true to your idea. This not to say you ignore the wisdom of people who have best interest and can give insight which might also be concern. However we all know of people who are negative for the sake of being negative.
So now the challenge is to discern the difference and keep true to the vision.
