I don’t see it as “marketing” onesself, per se.
Yes, humility, teamwork, and so on, are very important aspects to show. But it’s, “Show, not just tell.” And too many kids can only tell.
It’s really the same as going after any competitive venture.
And “qualified” is this ‘more than minimum.’ Not just stats and titles.
The glossy brochure kid isn’t it.
