Most people don't make it. Most people are not going to get out of the 5 figure ranking at Amazon. Most people are not going to have a hit record. Most people are not going to make it to the Olympics. We live in a very competitive world and the playing field is not level. It never was and it never will be. You can't legislate uniformity of outcome.
So pretend you're going to fail. I remember hearing Robert Schuller the Christian pastor say years ago "What would you do if you knew you couldn't fail?" Then everyone ran out to do the things they wanted to do completely without preparing for it. Yay, thanks a lot, Bob.
So you're going to fail. Now what does your life look like? What do you do tomorrow?
