The money quote -

  These investors, including myself, know what you don’t, and they are not telling
  you. The minute you ask for money, you are playing in their game, they aren’t 
  playing in yours. You are at a huge disadvantage, and it’s only going to get
  worse if you take their money. The minute you take money, the leverage completely
  flips to the investor. They control the destiny of your dreams, not you.
