The fundamental principle of making money is to do no work. As long as you're someone who works hard, you definitely won't make big money.

Not working, only understanding trading and strategy, is the way to make money.
Don't rush to argue first; take a moment to think about one question:
What are the truly wealthy people around you doing every day? Are they moving bricks? Are they working overtime? Are they sitting at their desks from morning till night?
The answer is all no.
