@MasterZaitsevSorry, i forgot the /s. If you read the comment i was replying too you might be able to figure out what i meant.
@JanTouchTheSun"I believe if I knew all my opening theory and remember and know how to apply all of the themes in the Dvoretsky's endgame book I am a GM."
You made it sound easy. Not me. Learn some openings, understand the stuff in one book. Boom. You are a GM. Even when using an opening database you will rarely even reach a playable endgame. You simply have no idea how good GMs are (or how bad you are).
