I wish someone would have convinced me of this at 15. Or 20.
Even investing $50 per month, and never increasing the amount can give you a seven-figure portfolio. You just have to start early. A fifteen-year-old who invests $50 per month until age sixty-five, or a total of $30,000, will have an investment portfolio of more than $1.3 million (assuming an average annual return of 11 percent). While that may not be much help to you given your age, I’m sure you know a teenager who would benefit from this knowledge.
