No, seriously. Look at some Usher video's.
Honestly, I'm pretty sure that no one even cares how you dance. I'm also beginning to think that the best dancers are the ones that have no idea what they're doing, but do it anyway.
My ex-girlfriend is under the impression that I am one of the best dancers she's ever seen. A friend of mine talked to her once when I wasn't around and he says, "the only problem with Derek is that he can't dance". She reply's, "are you kidding me?!". Let me tell you a secret. *Psst* I
can't dance!
I started by moving my feet like I was tap dancing to a hip-hop song. And than I'd pick up on little patterns that I noticed I was doing and I'd start repeating them for a "I swear, this is an actual dance move!" effect. And it came off as cool! I caught people weeks later doing the same dance. Like they knew it was a dance move all along, psh. Pricks were stealing my moves, man.
Go ahead, be retarded. If you look confident when you're doing it, it looks cool.
Also, when I wasn't dancing, I watched others. I watched the people who looked the coolest on the floor and when it was my turn, I tried to do some of their moves myself.
But if you really wanna learn how to dance... If it helps with your confidence... Get some lessons.
