Frankly, I couldn't help but wonder if this wasn't a joke. You have 150 ways to "determine an investors ROI". Okay, so what? One way is sufficient, isn't it? And, although I have no idea what a "Financial Engineer" is, a financial advisor has to do a lot more than just determine ROI. The difficultly with self schooling and "self proclamation" is that there is no "standard" to measure your skills by. Even you have no idea how you compare to those who did go to Business School and were graded on standard tests. How can anyone else have confidence in you?
I have no idea what you mean by "putting nations in financial chains" nor what that has to do with what you are saying here.
