How do i achieve success in the music business?

I'm a 17 year old my voice has changed from tenor to b i'm a senior and i don't think i have enough talent. I have a voice its not fully developed and i don't want to go back to my girly tenor voice. I also want to learn piano and i'm only able to play by ear but i am able to make a toon in my head and play with my music software and create a beat but the music software won't allow me to record microphone audio. Ugh so many problems. Do you think with time say early twenties i could start playing at bars and maybe land a gig by late twenties if i try hard enough?
