Sabrina--
this is a tough one for me to answer briefly! I started dancing when I was 17...then my reasons were simple. I was passionate about it. I loved the craft or perfecting the body movements...but especially I loved the challenge of working with someone else. Partnership gave me a feeling that ballet and jazz had never come close to matching. I love the bond of partners...the ability to play off one another and improvise, as well as the support you give one another in reaching your potential.
Unfortunately had a pretty disagreeable partner...so I left dancing for 7 years. I returned after having 2 kids...and being a stay at home mom. I still love it for the reasons I mentioned esarlier...but now I have more appreciation for it. Dancing gives us an outlet to be expressive and emotive that most adults competely lack in their lives. It gives you the freedom to create with your body an expression of music...and it puts you squarely in close contact with another human being...something else that we sometimes lack in our society. I have found through competition that dance also creates friendship, confidence, and self-awareness. Not everyone responds positively to comps. but it feels like fmily almost for those who compete often.
Dance is a powerful outlet for many people, we all use it to transform our lives in different ways...it is the ultimate self-therapy...the reasons to pursue it are as infinitely diverse as are the dancers.
Good luck!!-Mal
