Twenty years from now you will know if they were right.  Won't matter any by then but that is about how long it takes to make it either way./  Have seen all of them, those who got something for next to nothing and squandered it away. Those who started with nothing and made it. Toughest course is probably to get it then build it for the next step.

  Take stock of whats there now. Knowing if you don't double it you will have failed.  That will put you under the same pressure as those of whom you speak.
