Why top Ivy Leaguers are the best sellers

Was having this convo with some friends of mine, who all agreed with this...

They sold themselves ever since they were 14 and starting high school. Selling admissions officers of their achievements, selling teachers and counselors of their desires and passions... that's the hardest part in the admissions process. The rest (getting a high GPA and high SATs) is secondary (since most applying to HYP have 4.5s and 2300+ SAT anyway - need differentiation) and honestly, pretty darn easy to obtain if one simply tries. And while they're about to graduate out of college, they're continuing to sell, sell, sell, branding and marketing themselves for consulting and banking positions.

Have to hand it to them, it's an awfully important life skill to have in this world.
