My one big vice is that I love cruises to the Caribbean too much.
My biggest flaw is that I get so wrapped up in work that I need someone to remind me I have a ton of vacation time I can use.
My best quality is that I'm very logical and don't let my emotions decide things for me. It's worked so far, being a Vulcan.
My hidden talent is that growing up my parents taught me to rock n roll swing dance and I'm still awesome at it.
