If you are your own worst critic that indicates that others think your ideas are valuable, but their opinion should be converted into money, so I should ask to those that give high value to your ideas to pay or to get a share of it. If they don't want to put a single buck in your pocket for following your ideas then you are not your worst critic but a realistic person. If they give you some money to continue, then try to change your mind, you have some value in your head.
