Knowledge of the entire Torah

Hello,
I am taking my first steps in the world of Torah, [I am 18 years old, and every day is dedicated to study]
And I have a burning desire to swallow the entire Torah, including all its roots and ramifications – something that, in my view, is very achievable.
My question and request is whether the Rabbi could write me a sort of guide to places, destinations, and grades that I must pass through in my academic career.
How to build the foundations? What insights and understandings are critical to building a complete structure of understanding and knowledge of Torah?
For example, where is your recommendation to linger, and first study in depth, and where to first study fluently and then go back and review, which books should not be given up, and which books can and should be skipped [I assume you won't mention names, but my intention is perhaps a guiding principle]

I know that my question is broad and general, and different from the usual type of questions that you answer – but I long to find a straight and systematic path in studying Torah, without the additions of verbs and perverse and unnecessary customs.
