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.
Some people will get a lot of money in shares. The difficult question is when to buy and when to sell. The hype will fade and shares will fall down very quickly but to win in this game you have to determine when it will happen. I don't know when, but I think that the fall down will be the extraordinarily stiff, in one day or two a complete collapse. Wait and see.
