well you could start by singing randomly in the subway and get moneys.

or sing in a old bar and earn very little. gotta be sterotype 40's bar too. were you sing and sit on a piano.

or you record shit and put it up someone on youtube.

and remember use your stomach and lungs boy. dont fuck your throat. blah.

maybe ... show us something...?

You can go to Korea or Japan, they'll tell you what to do!

Create a hit song, something catchy and worth remembering, it can be as ridiculous or complacent as you want.

Start doing small time gigs in venues such as pubs or nightclubs.

Sign record deal.

Do crack and LSD.

Go through Diva phase.

Make comeback tour.

Get assasinated.

Simple.

I would start with some voice lessons. Record yourself at intervals to see how you progress, it'll make you feel good!

Pick up an instrument that might help, even if you don't use it for performing. Start networking and finding places to perform, even if not for money all the time. Stuff like that~
