I'm not saying this career is like a video game, but in newhire training for sims for both the CRJ and A320 I thought of it like a video game. Every approach is like scoring a goal and here's what I have to do with my players to get everything in order (prepare the approach), and then here's how I will execute the play (to score the goal). For me it was a mental thing and it translated really well. In the hotel, I'd sit on the bed corner and then chair fly, literally pretending I'm holding a yoke/sidestick and making all the hand movements to simulate pushing AP on, heading, altitude, and even using a foot to slowly pushing the rudder for V1, etc. etc.
Another advice for the sim would be nice, gentle inputs. Both my jet sims so far have been much more sensitive than the real plane. In the sim, there's no rush. V1 cut, slowly start getting that rudder in there. Don't smash it in. Pitch for that target (~10 degrees depending on plane). Smooth rotation to it, take your time. Once the AP is on, I go into video game mode of pushing which buttons. To reiterate, I'm not saying I view the job like a video game or that it's not serious, I just mean in terms of sim world and how to tackle it mentally.
And as others have said, make sure you get the flows and callouts down cold.
