Thoughts on social isolation?

I see some mixed views from MGTOW on being social and having a social life, I'm 17 atm, so I'm essentially undecided on the matter, but I'm already a more introverted individual.

Here's a Schopenhauer quote though, "Rascals are always sociable, more's the pity! The chief sign that a man has any nobility in his character is the little pleasure he takes in others' company.”
