Do you mean studying professionally, as in studying is your job?
Or studying like a professional? Studying the way a professional does?
Unfortunately, I don't think that would work either. You still need to climb the mountain before you can adopt the methods they use to stay on top.

You already have a notebook. Here on chess.com, what you do is recorded. It says you play lots of bullet and don't do lessons. You also don't do many puzzles. A lof of people believe that tactics training and puzzles are useful to improving.
