25. Invest Your Money.

Put your money to work for you, instead of working for it. There are all sorts of routes you can choose to go with from buying individual stocks to index funds, bonds, CDs, and beyond. You can also get into things like earning dividends, day trading, binary trading, forex, and so on.

While those options can seem confusing and complex at first glance, you really can’t go wrong following Warren Buffet’s game plan. Just buy stocks from companies you love. Hold those stocks forever. Don’t sell them in a downturn, instead buy more. If you don’t wish to buy individual stocks, invest in a simple index fund.
