Facebook, while possibly single-handedly delaying the writing of my novel, is a wealth of, not only useless information but, rare gems that are hidden amongst the idiocy.
I will not overwrite this post because the speech that Jim Carrey gives to a graduating class speaks volumes and it is something I hope everyone has a chance to listen to, very closely, and take to heart.
Several lines in his speech truly tugged on the strings of my reality. It really is time to ask the universe for my dreams. It is time to stop making decisions out of fear, disguised as practicality.

I echo your feelings about FB: while I wade through the crap in a despondent mood, I will stumble upon some gem that will interest/provoke me or just make me smile.
And those smiles are thankfully worth wading through the crap.
