If money could guarantee someone peace of mind, then the man in person would've spent half of what he's acquired to find peace but what we was going through was beyond his wealth, and he's a prove that one can have all the billions and still not get peace or happiness. I might be wrong though but what's your opinion?
Money doesn't guarantee happiness, it's true. That's why successful people end their lives in bad ways, and make no mistake, there are also many poor people who end their lives in bad ways. It's all because they have no purpose in life, no mentality, and can't control their emotions.
If rich people commit suicide, they usually fall into poverty and are unable to start from the bottom, perhaps this is one factor. And it could also be because there is no purpose in life, if he becomes rich and has everything but does not have a purpose in life then his life will be empty. After all, having a lot of money doesn't mean he can control his own emotions and mentality. Many rich people commit suicide because they don't have a goal in life, they start to get bored with their life, maybe because in difficult times they have their own targets, then when they become successful they start to get confused and don't know what else to do. so they commit suicide (this happens a lot in Japan).
That's why I agree with Bill Gates and Melinda Gates, they are successful, their children are safe, they choose to help other people. why is that important? because they feel needed by others. Why do many poor people become strong? because they survive for the sake of their children. there is someone who needs you that makes you think twice about ending your life, there is someone who needs you to stay alive. So believe me, surviving is also a successful achievement.
