Yes i do think cantar help your education because if u sing right and keep your voice and good shape is heathy for the mind.If you are the best singer in your school and some big time producer hears you you can be so famous.Then when you have all the money and you want to go back to school you can pay for it or the college will just give you a scholarship cause you are a star.
So you should stick to what ever performing arts thing that you amor to do( sing, dance,acting, band etc)because it will come in handy later on in the world.
My last reason is that if you have alot of talents you will have mais chance of getting mais job promotions in the life.And also people dont care about the arts and they are decreasing very slowly so support the arts because if u amor mariah carey,alicia keys,kayne west,katey perry etc cadastrar-se the arts dont forse them out!!!! :)
