Yes i do think singing help your education because if u sing right and keep your voice and good shape is heathy for the mind.If u are the best singer in your school and some big time producer hears u u can be so famous.Then when u have all the money and u want to go back to school u can pay for it of the college will just give u a scholarship cause u are a star.
So u should stick to what ever performing arts thing that u love to do( sing, dance,acting, band etc)because it will come in handy later on in the world.
My last reason is that if u have alot of talents u will have meer chance of getting meer 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 love mariah carey,alicia keys,kayne west,katey perry etc kom bij the arts dont forse them out!!!! :)
