It's often said that we should choose our friends wisely, for many reasons. One of them is that the type of friends you have is a reflection of who you are. Contrary to this common belief, I have chosen to befriend all because of the nature of the Libran who rarely, if ever, bears a grudge against anyone. Another reason, which I feel strongly for at this moment, is because the friend must be someone who can compliment your own temperaments and make up for your own shortcomings, and in a way, balance your life by covering what flaws you have. For example, when you have a habit to shoot your mouth off without much thinking, you'd want someone who has a quieter nature who won't hesitate to stop you from making a fool of yourself during social / networking events.
Based on the simple economic concept of scarcity, in terms of time/money, should there really be some people whom we should not even bother to contact if the personalities clash? As in, he/she will not be able to stop you from blabbering your mouth off?
Some people are just not worth it.
