Know your risk appetite

If you're just starting out in the market, my advice is - To only invest with what you can afford to lose.

Trading or investing in the market is an entirely world in itself where one needs to invest time to understand the fundamentals of the market, and to keep up with the everyday news. It is also incredibly important to research before you invest and to make rational decisions that you can live by. At the end of the day, it is your hard earned money that you are using in hope to get greater gains. Homework is important.
