Of course money can change your appearance but it can not change your happiness in life. You may have money than anyone else but are you sure that you happier than them? You have much money, you certainly have a lot of friends. But who is your real friend? Who does always go with you in every situation? Or all of them are abusing you?
If you have too much money, of course you can buy everything that you need, but you only feel happiness at the moment. People feel happiness when they achieve something such as a goal, but if you can make everything happen without even trying or putting in any effort, your life would be boring. There wont be a point of living because you do not need any goals if you have all that money.
