Investing is the best thing teenagers can do to build long-term wealth and become financially free because each dollar invested as a teen will become worth exponentially more. This book, written by a fellow teen, covers everything a teen will need to know to understand and have success in the stock market, as well as provides an introduction to related topics including personal budgeting, saving money, and making money. We'll also explore concrete, real-life examples, and learn from the world's most successful investors. As the author, I wrote this book so investing can change other's lives as it changed and continues to change mine. No matter who you are, no matter your age and no matter the amount of money you have, you can invest, and this book will help you do just that.
