The Link

It's not about what you know, it's about who you know. Ironically, the latter seems to be the harder of the two. Knowledge is simple, you read a book, you go to class, you can do these things with your spare time, keeping up with people involves a much more invested use of your time. But most people just can't face the fact that they need to put forth the effort to make these relationships work.
These individuals believe that at some point if people want to find them then they will go to them, but all that's really saying is that they're afraid of denial, rejection, and getting hurt. It's one thing if you're putting forth all the effort and the other isn't, because then at that point you're being a fuckin' moron and enslaving yourself to the other person's will, but if you're too lazy, afraid, or whatever to even put yourself out there, you miss out on the majority of life's interesting moment, and being a coward.
In the sad connection to Barbara Streisand, people need people, regardless of what you/they say. Make an effort, make a connection, make your life interesting, because at the end of the day, a life devoid of friends, family, or people in your life is not a life at all.
