Want my family to be happy?

I am very impressed by your strong will and desire to make your parent happy. Two thumbs up for you!! One thing that I want to say, you do not have to focus on giving them back in the form of money; because if you cannot, it will make you disappointed. There are many ways that you can do to make them happy; you just have to find out what things that make them happy and do it for them. If they like to have a conversation time with you, then give them your time, spend time with them. If they like to see you happy and enjoy your life, then show them that you are happy and enjoy your life. If they like to get a kiss and hug from their children, then give them kiss and hug often. See, there are many ways to make them happy, not only related to money. But if you have money, it's good to use it for them in any forms that will make them happy. Hope you make it :)
