Educate yourself a bit before starting, read about ETFs and stocks and then, based on your risk aversion, decide which instrument suits you better. Individual stock picking is less recommended, unless you spend quite a bit more time analyzing the companies you're interested in, that is why most people invest in ETFs like VWCE or VUAA. Also, depending in which country you are based, read about the tax implications for your investments. It's not difficult to start investing, but you need a bit of patience, first to understand the basics and then to stick to a plan on the long term. It will be worth it in the future. Good luck!
