I want to win any ddk without thinking

So, after a 1.5 years of studying go almost every day and being played thousands of games, solved 1000 of exercises and watching hundreds of videos on YouTube I came with a conclusion: I need to learn to win sdk (on OGS) without thinking.

I know it is possible, many times I was told that it is just matter if good shape and general feeling of direction of play. In some of my games this works (some basic reading skill helps, but often you just keep everything connected, separate weak groups and whatever Triton Baduk tells in his videos : ) ). However, my goal is really win every possible game.

Currently my rules are 1. Resign if I make a mistake which I can recognise (often it is something like 15 points mistakes accounding to an AI). 2. Resign if the game is even in middle game (from my feeling, which is often coinsides with AI estimation in +- 7 points) (I know that endgame is important to learn, I even know basics there, but it is not my focus right now).

Currently I am myself a ddk, but I don't want even to achieve anything via risk and aggressive play (I know how this works, play random moves and confuse your opponent). Only very solid, protected game without any possible threats from average ddk player.

Questions:

1. How many players here can win any ddk only on instincts?
2. How much reading is involved, what is average depth? I usually read 2-4 moves (from the 1 person, so 4-8 total) for some familiar situations, however usually middle game or complex tsumego like stuff is harder. Maybe I just need to in increase this skill?
3. What general principles do you follow? For me they are: a) Keep your groups strong enough before attacking a weak opponent's group b) Reduction over invasion c) (ddk level) keep joseki as simple as possible. I start woth two 4-3 poins and never regret at this level. d) Some general patterns like hane in a head of 2, 1-2-3-jump and some other stuff e) strong group = 2/3 following properties: 1. Having a base, 2. Having an eye shape. 3. Having an access to the center.
