Nada. Yes, money is essential to every day life and it can buy almost everything as we all say. But it can’t buy happiness. Happiness is like a rating system for life. We are happy when you get what you want. But sometimes we don’t know what we really want. It’s always changing. You are happy at one moment. And next minute, it’s all gone. We can’t help but collecting problems or reasons that stop us feeling happiness. And it hard to change who we are. I guess the only solution to that is savor the moment and let it go when you can.
