Quick reminder the school you went to and the company you work at are all part of your brand and you want your brand to be extremely exclusive. This is all effectively one giant sorting function. So the best high school students go to the best colleges. The best college students go to the best companies. The people that work at the most prestigious companies will then continue to work at other prestigious companies. It's just this revolving door and massive sorting function. And once you get into a prestigious company, a prestigious college, you're effectively exclusive and you stay within this brand. And if you haven't figured out how to transfer into this exclusive space, figure it out because once you're in, it's easy to stay in.
