Pro Tip: The Power of Starting Early

Time is the most powerful factor in compound interest. An investor who starts at 25 with $500/month will have significantly more at 65 than someone who starts at 35 with $1,000/month — even though the second person invests more total money. Start as early as possible, even with small amounts. Consistency beats timing.
