Everyone, except perhaps Grizzly Adams, needs other people. Some days you need a new client for your Rails expertise. Some days you need a plumber. You need those guys who stock the grocery store in the middle of the night. And you need real life friends. Friends who don't sap your energy or tell you what to think. Friends who will scrounge up a car for you.
Edit addendum: Hillary used to say, "It takes a village to raise a child." Yeah, whatever. What I'm trying to say is, it takes a community for thriving and emotional health. And don't let Ayn Rand tell you otherwise. There's no shame in hitting a point where you can't "produce" and you need help from others. You're not self-made. No one is. And a person who needs help is not a loser. Or a "looter."
