Go open up a Demo account and practice, practice, practice for 5 years. . Read , read , read. Read "rich dad, poor dad".... Market wizards.... and High probability trading for starters . If you really WANT to go to college then take up finance or economics. My buddy is in economics right now and Ben Bernanke is the author for the book in his macro class. LOL what a scam of a system but thats a different story.
Be frugal and save most of your money . Alot of my peers bought booze, weed, fancy cars, big tv's, videogames and other BS ON CREDIT... Don't go down that road, be wise with your money.
"rich dad , poor dad" is the book that started getting my "financial " mind to think. If you know little about finance then "rich dad, poor dad" is a good one for starters. Stay realistic on your journey. It's just like becoming a doctor. It takes a time and hard work.
