Aspirations

Anyone else got some crazy dreams they are pursuing? I wanted to be a professional soccer player out of high school and had made the final tryout but got injured for 3 months during it and life got in the way after. Four years later, my dream now is to become a Rockstar singer. To be up on stage and share a sort of energy and love of the moment with the crowd. I've always loved singing and going to concerts, and it's become my undying passion to take it as far as I can go. Life is short and we only have so much time to pursue our dreams and take part in that which makes for a truly memorable life. It can be very intimidating yet what is the true harm in failure? Atleast you can live with no regrets and move on, yeah? Anyone else have what some would say are improbable aspirations?
