Those who say that money cannot buy happiness, are absolutely wrong.
Firstly, money can give you a comfortable life. You can buy and do whatever you want with it. Having money with you reduces the fear of your mind. If you have money then people around you will start taking care of you, Will give you respect. And you can do whatever you want.
And I don't think you will get sad when you step down from your brand new BMW, and people call you affectionately.
And the more money you have for this, the better it is, meaning the more money, the more happiness you will get.
