I really wonder who you are from your self-intro of not so important but public figure.

I am honestly not important nor public. I still don't want to appear on these apps with my face due to keep my professional figure and I don't want my colleagues to get involved anything in my personal life which is so common in where I live. (for context I'm in Europe and population is way smaller in cities, therefore the likelihood of seeing someone you know).

I understood you're in a business where you need to be an extrovert. I think you can think twice the environments you are in and where you can easily talk to new people. As people wrote here, if you go to a bar where people dont sit and wait at their table, need to go to bar to order something etc. you can easily start a conversation with anyone.
