My Dad bought some stock for me in dividend reinvestment plans (look up DRIPs) starting from when I was 8. I loved getting statements in the mail every quarter, seeing how the dividends I received each quarter increased because the previous dividend was reinvested. And then about once a year the dividend rate would increase, and my dividend would jump higher! Plus, I started reading annual reports to learn more about the companies, which then taught me a wealth of other knowledge - electricity generation, oil exploration, even paints.
Now I look back and can see the value of buying high quality stocks and holding forever. Plus I've learned a ton about investing, finance, business, and more.
