I don't care about people who sell their souls to the devil in the hope of becoming famous and rich because the fame and wealth they have can also be lost when the time comes. But when it comes to happiness and satisfaction in our own lives, it only depends on how much gratitude we have after we earn income from our own efforts. Because people who have income and are grateful for what they have received are people who can always be happy with their own lives, while people who are not grateful for what they have received will always feel lacking and unhappy with their own conditions.
Being rich and famous does not guarantee you will live happily. But having gratitude will make our lives happy. I do not deny the fact that wealth can make you happy. But if you do not have gratitude for what you have achieved then greed will enter you. We must work hard to get wealth. Because with wealth we can do many things to make us happy. Like having a comfortable home, seeing our family can have dinner together, or share happiness with other people around us. But on the other hand we must continue to appreciate and be grateful for every process we do.
