If you can't take a finger wag without shoving someone you need to go on an anger management course. He's more than welcome to fire the guy afterwards if he really didn't like it rather than shoving him, he is after all in the position of power here and why the shove is so bad.

He's been taking it seriously since before F1, just look at the money spent and training to get him through F3, they even hired a Ferrari F1 guy to run the team. He even paid Williams for private F1 tests once he arrived into F1 in an old F1 car, engineers and hiring the circuit for himself. Hes had a ton of training with the top driving coaches all the way through.

Last thing I'd accuse him of is not trying hard or having access to the best resources. What we see now is the best he's going to get.
