become a good dancer

I have always been into dance and have gone to clubs but given up after a while i dont know why. im not saying i want to become like a professional dancer well i wouldnt mind it but i dont think i will ever become that good lol! and im not into like ballroom dancing or nothing im talking about like modern dancing like what you see in most music videos lately (and no i do not mean going around like a complete slut next to a black rapper) i just want to start dancing again so i actually have a good hobby lol! i want to become good at it too cos im not really good at anything i dont think!:( xx
