It could be useful for the student to be told by the instructor on day one that it is not a race,that going solo at x hours does not make you a better pilot,and that the world is full of flash bas****s trying to be one up.
Lister, I tell my students something similar, very early on. The difference it makes is precisely...nil.
Most pilots are competitive high achievers, and even if something isn't a competition, they'll somehow make it into one.
