~ There is knowledge that are not publicly available because some of it has price and that kind of knowledge that we should seeking for us to think outside of the box that can helps us to achieve financial freedom.
Sounds a bit cryptic to me, but overall I agree that if you want to achieve financial freedom, the lack of knowledge is the main obstacle. I personally think that all the knowledge you need is publicly available, but it has a price, yes, it is true. The price you pay to get that knowledge is your precious time: instead of hanging out with friends, or whatever, you study hard. And yes it's hard, but it pays off.
And the most difficult and rare knowledge and also of high value is Experience.
so that someone who can always learn from experience will always have an advantage over others. At least we can't give up. and keep trying to reach your dream. Achieving financial freedom is everyone's dream. But it is rare to achieve it. And when we can't achieve it, it doesn't mean we have to stop. what we do is start to evaluate and try again. because everything can only be achieved gradually. and of course requires patience and perseverance.
Your personal experience is very important, but only when you have some theoretical knowledge to test it on practice. Without that knowledge it's like reinventing the wheel by yourself. With help of the internet we can get statistics on experiences of millions of people, and it is very likely that those data are more important for achieving your financial freedom than your own experience.
