Start from zero

I decided to start from zero in studying chess. I played since 4 months, but in these months I had bad study habit. Now I would start from zero, studying well and stop playing blitz, only online chess. I'll spend a lot on every single moves, taking notes and analizying well, to really improve. I have these chess books:

-Understanding Chess Move by Move (John Nunn)

-Silman's Endgame Course (Jeremy Silman)

-How to Reasses your Chess & Workbook (Jeremy Silman)

-Pawn structures chess (Andrew Soltis)

-Learn chess tactics (John Nunn)

-Back to Basics: Tactics (Dan Heisman)

-Understanding chess middlegame (John Nunn)

-1001 deadly checkmate (John Nunn)

I would start studying "Understanding Chess Move by Move" and "Back to Basic: Tactics", maybe also study Morphy's games, to learn from his tactical skills, what do you think?

Morphy and Heisman are good ideas, but Nunn is probably too advanced for you at this stage.

And what about endgames book?

I think "ProfBlunderfelt" sounds more geniune and organic.
