<prompt> Human: Im 18 and have amassed around 1400 dollars and figure it would be smart to begin investing now. The only problem is, I have no idea where to start and stop. Got any solid advice?  <response>: The best place to start is to learn about the various types of investments available to you, so that you can understand the ins-and-outs of whats out there. I would recommend reading the Investing section on the sidebar and learn some of the terms at Investopedia. A lot of people here really like index funds and passive mutual funds with low expense ratios, and I agree with that philosophy.
