I built up a net worth of $30,000 this year. What are goods ways I can use my money to make money?

I made more money this year then any other year so I have been wondering if could use some of that money to make money since my liabilities are relatively low.

I was thinking of doing things such as investing in stock market, drop shipping or small scale start up investing.
