How do they look for contacts that add you in a professional way? (I will not promote).

Hi, guys , I'm writing this from a place very far from where you are, I'm from Peru. Here the culture is very different, since I was little I was instilled that "if you don't have a profession, you are nothing", I finished a technical career and I am currently looking to undertake independently developing personal projects, but somehow I am afraid to launch my product, make it known, leave everything and stay in nothing. I was always surrounded by the same thing of "if you don't have a profession, you're nothing" so most of the people I know follow this ideology, I want to change this in myself, but believe me it's very difficult in an environment surrounded in this way. I often research and watch videos of people who are in the US, Spain, etc. Surrounded by people who have the same passion and similar goals. My question is: How do you get to know this network?
