What do you really need to work as a freelancer?

Basically you need a decent internet connection, a working PC, and the ability to get paid (so a bank account, VAT number if you're in Italy). The rest depends on what you want to do, but the most important thing is knowing how to manage your time on your own because there's no one checking up on you 😅 and you need to be good at finding clients, at least at the start.
