As the other person said, it can take hardwork, lots of failures (yes you will fail, before you have the success, that is part of life. Also you will need to fine tune your business skills or find people to work along side of you.
Keep your costs low, and profits high and not the other way around.
(You could find a long lost relative who is a millionaire and they give you all their money - maybe a joke but could work)
But can I ask you a question, how do you define rich ? to some people it is debt free, lots of money, cars and holidays, but they could be lacking health and loved ones.
Now you could turn this on it's head. You can have the poorest person living in a mud hut somewhere in a far off country. They have money, little food. But they have loved ones, they are happy, but to some they are poor, but to them they are rich.
They have no debt, lead a happy and healthy life to them they are mega rich.
Hope this helps
