Who knows how new or do I need a mentor?

There is a task in Bitrix. But as I in this system are still floating around. Nor did even a single major project or store. So the usual video courses and read a little documentation.
Well, you know what an educational website this is all wrong.
php js css html know is normal.
Question.
1) All you have to reach all in solving non-standard tasks?
2) if you do not know what to do or not Mature enough ( how to say )?
3) as time spent to become a guru in it?
