Earnest (refinance your student loans): Same idea as above but on your student loans. There is $1.4 trillion in student loan debt outstanding.

Real estate is sometimes a good investment, but it is expensive. Investing in the stock market does not have to be expensive, but it can be risky and unstable.

There are plenty of factors to consider when investing, so make sure you think about it rationally. Talk to experts or friends who are experienced in investing before making a decision.
