Try taking some vocal lessons, or if you know someone who is a great singer, see if they can give you advice or maybe even tutor you. And maybe if you're still not great at singing, maybe you can learn to play an instrument.
You don't have any friends with good voices? There has to be someone you know. What about reading about vocal techniques on the internet if all else fails? I wish you luck with your endevour, music is infinintly precious.
join a choir and let your voice fill the harts of all.
You have to go to the Hollywood.
Where are you from?
