Agreed, also depending upon you job requirement you might / might not have to touch front end stuff such as html / js etc. Knowing the basic is a huge plus though. My biggest wall trying to learn myself was understanding OOP after understanding that i think it is lot easier on the back end. The other one was understanding how front -end connects with back end , meaning when you click a button in your webpage how the server will listen and process the classes / functions etc. Yes you will need 6 months of hardcore studying and practicing , depending upon your learning curve you will land where you deserve.
