Both of my daughters were like you. They loved to dance and participated in dance competitions when they were young. They liked to twirl batons as well. They followed their passion and applied to several colleges to pursue a Dance major in college. Although they didn't want to be professional dancers, their passion was so strong that I felt compelled to support them. I did ask that they also have a dual major. Long story short, they both graduated from UCLA with double majors... one of them dance. Neither went on to dance professionally, but they wouldn't change a thing. One is a successful realtor and the other is an executive recruiter living in London. The discipline and lessons learned through dance is foundational to many life skills. If you are able to follow your passion, go for it. Live life with few regrets. Keep your eyes wide open for creative ways to leverage learnings to apply to other opportunities. Most people change their occupations at least seven times, so view it as a series of experiences that build upon each other.
My daughters have friends who were fantastic dancers. Some danced in professional dance companies and for an NFL team. One now spends most of time choreographing other dancers.
Life is about experiences and continual learning. Go for it!
