That's just your assumption. I'd say typing is probably the sill that's easiest to optimize. Even if you just type 10% of your time, cutting it down by half is a significant improvement. Also, proper typing will boost your confidence and free your mind for more relevant things.

To draw parallels with Jiro: Cooks learn how to properly use a knife before they're even allowed to cook. They do so by exercising preperation over and over.
