I want to do something with my life?

Hello, I'm 15 and today I've just realised i want to do something special with my life.Something Sucnificant. Something Different. Something that will give me a purpose. I don't neccerserally want to be famous, but maybe inspire people. I envey musicians like Hayley Williams and Christina Grimmie and although I play piano I don't feel like going up the music route. I get depressed somethimes about not being someone. I love my friends, my music and my Parents. I'm well off, I'm predicted straight B's and I don't; drink, take drugs or smoke. I'm kinda like a plainold boring me. Which is sad i guess. I'm probably not the first person to bring up this whole (do something with my life etc) but back to the whole question. I WANT TO HAVE A PERPOSE. iwant to wake up everyday feeling happy and making everyone around feel the same
