18 an stressing like crazy over getting rich

Hello everyone, just turned 18, using a throwaway here. I am from a eastern european salary where the average salary is about 800$ a month and I’ve been working as a photographer since I was 16 and saved up around $10k. Now 18 for around 7 months I’ve been losing sleep over getting rich and a way to start a scalable buissness, something I can put my time and effort in and something that can buy me the freedom I seek. Any suggestions on what business should I venture in to and how should I finance my money ( keep in mind I have them all cash )
