The most important skill to learn if you want to be hyper-competent is patience.
Think about this: the best drivers (say, the top 20% in terms of efficiency of movement, control of the vehicle, situational awareness, etc.) get stuck behind bad drivers far more frequently than the worst 20% of drivers do. It’s simple math: if you’re a very competent driver, you’re moving around more efficiently and you’re seeing more road overall. If you’re average, then sometimes you’re stuck behind a bad driver and other times you’re the bad driver someone else is stuck behind, and it all washes out. But if you’re very good, then most other drivers are by definition worse, and you’ll end up stuck behind someone who is hindering your movement far more often.
Hence, if you want to be very good at anything, patience is an essential skill.
Lots of technically competent drivers end up dead because they didn’t have the patience to avoid a road rage incident or let their tempers cloud their judgment. In any sphere, lacking patience can easily eat up any advantage you have from skill. Plus, you’ll be miserable all the time, since you’ll almost always be interacting with people worse than you at the thing in question! If you can’t be patient with those people, you’re setting yourself up for an awful time.
If you can’t keep a cool head behind someone doing 30 miles under the speed limit in the left lane with their blinker on, then you can’t do anything tough.
