Your system has a bio-chemistry.
This bio-chemistry is intricately coupled to the mind and the nervous system.
When your money is on the line, your mind and your nervous system start reacting.
Money-on-the-line means automatic emotional involvement. Period.
Many of those who talk about investing / trading do not have their own money on the line.
Thus, they are not qualified to talk about investing / trading. Do not listen to them.
Instead, listen to your own bio-chemistry. It will teach you.
That’s what money-on-the-line does for you.
