I read a book on Object Oriented Concepts, oddly it wasn't part of the required reading material while i was in UNI but i had a class in 'vb.net' and 'advance vb.net' in my second year, my dad told me to read that book and said everything would make sense, he wasn't kidding. i understand OO so well that only thing i learn now is just the syntax of a language I want to pick up that's how i switched to c#, learned java and python. ALSO YouTube and Lynda.com helped😎
