Dance, even if you have nowhere to do it but in your own living room! I've definitely danced in my bedroom, living room, kitchen, and even bathroom. It doesn't matter where you are when dancing is who you are!
Don't practice until you get it right. Practice until you can't get it wrong. -Sounds like my drill team coach. "Practice doesn't make perfect. Perfect practice makes perfect." But hey, we crushed the competition every time!
