Keep in touch regularly with your friends and acquaintances after you no longer are in the same school or company. When 25, it feels like you will know and remember them forever, and vice-versa.

(Of course, I remember the guy who was in a group I ate lunch with in grad school who ended up running Google 25 years later; I don't know if he remembers me...)
