Where do I use my knowledge?

I was wondering I don’t know where I can use my knowledge of coding! I just thought i know how to code but don’t know where to use it so it can be seen to others on the world wide web(Internet).

I’m still studying yet, so I’ve never worked in this sector. But I’d say that a good strategy is to create some personal projects to show your skill, then try to apply for some job or some start-up
