Now we know!
I was wandering around on TVTropes the other day, and I happened upon the article And Knowing Is Half The Battle. Upon hearing that iconic statement, everyone always asks what the other half of the battle is. And everyone on the internet will gladly answer "ha ha, it's violence! I'm so witty."
If you'll forgive me passing that particular comedic gold mine without my pickaxe, I'd like to put forward that I think the other half of the battle is actually putting your knowledge to use. Knowing something is important, but if you don't act on it, you're only halfway there.
By the way, I'm not dead.
