How can I make my voice better?

I think I have an amzing voice, and people tell me that too!
but how can make it better? and how can I control it the way I want, cause sometimes when I sing at loud and scream you know, it sounds good like celine dion, but sometimes like for one single second like it cuts its self and comes back! so the whole song becomes bad!! what should I do to control my voice better ? and what should I do to feel the song and sing it from my heart ? how can I feel the words?

singing lessons my friend got them and now she is a great singer she was good before but after the lessons she learned how to use her voice different ways to do differnt pitches

get singstar on PS2 ...it will exercise your vocals

u should take singing lessons that always works
when I was in seventh grade I was in choir and my voice started cracking up and I started to do these voice exercises ma teacher thought me so get some lessons they always work :D

thanks everyone!! I'll get those lessons!!!

drink a little bit of honey before you sing- it coats your throat

I'll drink honey! I think it's a great way!! cause I've tried honey in other stuff! like when my throat is hurting me or my stomach or any part of my body, I usually have some honey! but I didn't ever think about having it before I sing!!! (LOL)
