In order to make money, people who don't care about their health win and lose to themselves. What do you mean?

Don't care about your health in order to make money, which means that health is more important than money.

I won the money and lost it to myself, probably to express that there is no good body to enjoy material life, and no amount of money has any practical significance.

Therefore, people should not be slaves to money. Health or life is more important than money.
