Only make it active if you have influence on the outcome (i.e., starting your own business). If we're talking stock investing, you'll just get eaten. Which can be a good lesson, but it's one you can skip if you want and go directly to index funds. :)

You can use your money to generate passive income, or you can use it to get leverage (retaining more of a percent of your startup; taking a risk on a risky but better job; etc.). In either of those paths, do it smartly.
