It's hard to close your life off in a healthy way. You have to think hard about things you probably would rather just not think of. Just yesterday a friend of mine miscommunicated with me, causing me to drive 45 mins in rush hour traffic to wait for him in an empty bar for two hours before I went home.

I was livid. I fired off an angry text when he asked me where I was and he chose to argue rather than apologize. In these kinds of situations you have to decide when, why, and how, and whether to cut them off.

I decided that I would use the same rule for him as I do for my lady friends. Always meet somewhere I know and am comfortable with, never somewhere new. That way if they don't show up it's not a total loss. Also never drive anywhere but home, the coffee shop, or my bar right after work. The better and more flexible and more intelligent boundaries you put up, the more and better people you'll bring into your life.

But it takes fearlessness and guts.
