Yes, I had a mentor.
Almighty Google.
But no, not a real one. It was a hard time of no mentors, when search engines were stupid, no GitHub, no StackOverflow, it was a time of useless books, CDs and time when you were trying to ask google things you had no idea how to call.
Yet, I've randomly found a local web dev school and it helped me to move forward, by that time I've already learned basics/mid of HTML, CSS and PHP on my own. Yes, good old times without JS.
