Learning about money while you are still young is an awesome idea. Let me give you a few ideas that young people can use to really win in their financial lives.
Being realistic is key. And winning with money is realistic! This means you should use common sense, investigate investments, the markets, and the opportunities you are interested in. Read the fine print. If you were to take on debt, ask yourself if it would be worth it, or if the debt would be like an anchor. Again, be realistic. Look at the real consequences of the actions you could take. Good actions should be turned into habits.
Consider entrepreneurship. Write down business ideas. Learn the skills you need to succeed. See if your business idea is feasible by testing your product or service. If it is, type up a business plan, and get to work. Make the phone calls and do the web searches necessary to find the information you need.
Join a club or society for young entrepreneurs. Earn a business degree. The more you can learn about business, the better off you are. Being around and networking with other goal oriented, ambitious entrepreneurial types is a boon to your success. Being around the total risk averse and the complacent is not a boon to success.
Work hard at your job and / or at your business. Make a good name for yourself. If a job does not work out, do not trash your goal of being rich. Just keep plugging away and learn from your mistakes. Sales or customer service would be a good starting point if your first job is not running your own business.
While (and if) you live with your parents, sock away as much money as you can. W. Clement Stone once said, "If you can not save money, the seeds of greatness are not in you."
Learn about investments, by taking an investments class at your high school or college (taking a few more classes is better). Economics is good thing to study too. Finance and economics are tough courses but are very worthwhile. Read extracurricular books and read about your interests.
Winning with money is not always easy. Self discipline, sacrifice, frugality, hard work, managing risk, reading books, and holding on to your long term vision are essential to your success.
