There is no age limit when it comes to earning millions these days. There is also no minimum age required before a person can become a millionaire. It is all but a matter of goal-setting, determination, and hard work that can get you to your first million.

In fact, there are even a surprising number of millionaires who have not even stepped on to college just yet. These are not the rich kids who were fortunate enough to be born with a silver spoon. These are the kids who just really know and understand how to make money even at a very young age. Here are a few of them and the most valuable lessons you can learn from them.

Christian Owens

According to LifeHack, Owens earned his first million before he was even 16 years old, by learning how to do web design by himself. He started working with Mac Bundle Box by offering simple and discounted Mac applications. What Owens did aside for pursuing his passion was to save people money by offering something for a lower price.

Cameron Johnson was only nine years old when he launched a card in 1994 called Cheers and Tears, according to Entrepreneur. When he reached high school, he moved into online advertising and software development where his earnings reached $400,000 a month.
