The author tells us the through way to Financial Freedom is to make many copies of your work product and sell them. For example, to be a bestseller, ?to produce Coca Cola, or to make a online platform. etc.

The author also reminds ?us never regard F.F as an ultimate aim. Never have a thought such as 'If I had a lot of money, I could …' ?Otherwise, you will think things that are benifit for you to achieve your goals of F.F seems very hard and tedious, comparing with things you should have done after you achieved F.F. If that, you would probably be disappointed with the present situation and even give up .

As the author says that F.F. is just a milestone of life. The most important thing is growth. We should always 'wash our brains 'lest the false concepts and thoughts are full of our brains. ? To measure whether a person 's brain is clean or not depends on the following two criteria. ?First, whether a brain is full of clear, accurate, correct concepts or not. Second, whether there is a clear,accurate,correct link between these concepts.
