Think ahead a few years in your life.
Imagine you've now spend $9,000 of your money and invested thousands of hours studying.
You are now a NM.
What will that mean for you? emotionally, socially, financially?
You ask, if it would be a "good investment"?
Now, imagine you've invested the same $9,000 and thousands of hours in some other training, perhaps in business or some skill where there's a plenty of work, that pays $50, $100, or more per hour?
Which path do you think will give you more of what you want?
.........and become a master (at least NM) within 5 years.
Do you think it will be a good investment?
