I have no experience in being in shows or anything like that but I really would like to become a singer and become famous. Im turning 18 in May and I really would like to know what I would have to do in order to get to Hollywood? I know this sounds unrealistic but its what I've always wanted. I can sing a little bit nothing major. Im thinking about being in my school talent show this year and hoping that someone will record that and I could post it on YouTube.I really want this. Can someone tell me what I have to do in order to start a singing career?

You will need:

Personality
Talent
Lots of money
An agent
A good break
Lots of time

First though, singing lessons.

So how many years have you taken singing lessons.
Do you have a voice coach ( OK I know you don't but you will have to)
Many today also have life coaches to help them plan their life.

But you start by learning music, learn to read it, and sing.

Then you start singing anywhere you can, you don't start at Hollywood, you start at a local open mic, perhaps a nursing home, the Elk club and so on.

I was thinking about starting with YouTube videos... I can sing a little bit and I have a great personality but I never took singing lessons
