why you should study / Organize previous data

why you should study :

I can manage my urgent heart.
It May did not depend on other news.
You can reduce the risk that exists in your investment.
I think number 3 is the main reason.
When investing, the risk may be 30% for some, but while studying, it is called hate.
Because risk turns into risk-free.

Organize previous data :

When I was just studying financial knowledge.

There are a lot more than I thought I had written so as not to forget.

I would like to compare it with the present and try again.
