It's helpful for people to find a second home, a community that supports you. A place where you can go and find joy when your life gets stressful. For many that's their church or an extracurricular activity. For me it's dance. Even if you're not the best dancer and trust me I'm not, you still feel that the others students and the instructor supports you.
I have made many friends from all the studios I've danced at. Even if I don't dance with them anymore I'm still in touch. The little girls look up to the older dancers, dreaming that they will dance like them when they grow up.
Dance helps grow your ability to be motivated and reach for your goal. I always wanted pointe shoes and got them about a year ago, which was amazing. We found out that my class would be able to have a fitting for the shoes. I was so excited. We got the order in and my shoes were too big. I was devastated (a bit dramatic), it took three pairs of shoes to find my match. Having that goal helped my strive to be a better dancer and work harder on my flexibility and technique.
