Never let anyone else manage your money! No one care about your money more than you. If you don't understand the stock market ... well now is the time to learn.
1. Open a brokerage account in your name and place your funds in that account. Make it an IRA or a Roth account if you can to defer or avoid taxes. But a simple brokerage account at ETrade, ameritrade, Schwab, scottrade, etc will do nicely.
2. Buy shares in roughly 30 dividend yielding companies from differing segments of the economy so you are not placing all of your eggs in one basket. Google "Dividend Champions" and "Dividend Achievers" for lists of companies of which you would like to be a partial owner. Not every investment will be successful and a couple will fail, but most will not and in seven years according to the "Rule of 72" you will double your investment and you'll be pleased you followed this simple advice.
3. Good luck ... you are now on your way to being an independently wealthy CAPITALIST!
