To be honest, investing has never been about working harder to make more money.
Making money is about riding the waves and going with the flow.
When it's time to work hard, work hard to make money; when it's time to rest, rest to avoid losing money, and you've already won 99.9%.
Someone previously used animals as a metaphor:
When investing, be like a lion; a lion sleeps 20 hours a day and spends the remaining time hunting.
Don't be like a sheep; a sheep sleeps less than 4 hours a day, spending the rest of the time grazing or being eaten by a lion.
