Embrace The Unknown
This might be the toughest thing for us to do.
The Unknown is something we are afraid of (if we believe what those smarter-than-us people tell us).
I say the heck with it. Everything is unknown until we get to know it.
Don't talk to strangers. Seriously? Everybody was a stranger once! I wouldn't know anyone if I listened to that crap :P
Embrace the unknown!
Do one thing you're afraid of every day! Do it as an experiment, you might like the results ;)
