If I have a lot of money, I will do many things.
I will help the people who are poor. If they have money, they will have nice life. They can buy many things for them. Their sons or daughters can go to school. So they will be happy. So do I.
I will help orphans. I think orphans are very poor. They have lost their fathers and mothers. So they are alone. If I have a lot of money, I will set up an orphanage. So the orphans can live in it happily.
Of course, I will buy something for me. I will buy some books to read. So I can learn a lot of knowlege. Books can open my eyes and make me be a useful person.
If I have a lot of money, I think I will be very happy.
