"Locked in."
I've known this guy for 4 years, and I'm still consistently impressed by him. He has a work ethic that is truly second to none, easily one of the most hard-working and dedicated people I've ever met. He's also an incredibly sharp guy, picks up things instantly and is always three steps ahead. But the best part is his character. Despite how hard he works, he is always down to help others, no questions asked.
