The interesting part for me is, I have used this advise for other people's businesses for as long as I can remember. There is something about building your own product though that somehow seems to overshadow your better judgement. I guess that is the differentiator (or possibly ultimate lesson to learn) for an entrepreneur. Can you throw out the ideas that don't work and pursue the good ones? I am still learning it, but it feels good when you get it right.
