How do you get famous?
Becoming famous requires determination, talent, and quite a bit of luck, and confidence! To be famous, you have to do something that's good like sing, dance, athletics, be the president, etc. You could start by singing, making movies, and doing things you are talented in.

Being famous also requires being discovered by the right people. A common frustration among talented people is that nobody will give them a chance. That is why performers do gigs and try to get on shows like American Idol and similar. As you can see, even being on one of those shows is no guarantee of success. Often, only the top 3 finalists or so attract any serious attention from anyone offering contracts.

A word of warning:
Do not run away from home to become famous. If that is your plan, then you need to have all your arrangements settled in advance. You should have asked for auditions with reputable people, and you should have your living arrangements settled before moving anywhere. Too many children get the notion to run away from home, move to the Los Angeles area, and try to get in a movie. It does not work that way. If anyone "discovers" you in that setting, it will likely be pedophiles and pornographers, not reputable people making decent movies and television shows. So you have to do your research and make your arrangements in advance. Having an agent will be beneficial, though it is not absolutely necessary. The road to fame will be long and hard, and you might not actually want it once you get there. Even going through the proper channels will be frustrating. You might write hundreds of letters, emails, and voice messages, and not have any of them respond.
