The goal of only doing what you've done before.

If you create a Kindle eBook and earn $1, you have $1. If you want to grow your business, you may decide that you will just do what you have already done. There would be no doubt that you could do it, because you had already done it. So you sell another book, and now you have $2.

Then you double that to to $4, then $8, then $16, etc. After 10 doubling, you have $1,000. Each time, you are only doing what you have already done. There is no question as to if you can do it, only how long it...
