To be honest, investing is never about working harder and making more money.
Making money is all about going with the flow.
If you work hard when you should and rest when you should, and don't lose money, you win 99.9%.
Someone used an animal analogy before:
When investing, you should be a lion, a lion sleeps 20 hours a day, and the rest of the time hunts.
Instead of being a sheep, a sheep sleeps less than 4 hours a day, and the rest of the time is spent eating grass or being eaten by lions.
