Poem by Taylor Mali
I found it first via @jonasnuts, who found it via @bitaites. I follow both, so it was kind of random for me to find it this way, I was merely catching up with the blogosphere.
This poem is certainly worth the whole 2:46 minutes of your life. If nothing else, it will get you thinking about the way people (and yourself) say stuff.
Don't merely act like you know what your talking about. Make sure you do, so you can not only speak with conviction but with proper authority.
These are demanding times my friends :)
