Sorry, but fame is a lousy reason to do anything - especially acting. Just ask Cameron Diaz:

But if you're interested in acting and performing, there are several things you can do:
- Take acting classes. Voice and dance lessons can be fun too.
- Audition for what you can - school plays, community theater, church shows
- Join other performance groups like choir, band, dance troupe, improv group
- Join drama club and compete in forensic speech/drama contests
- Read plays and scripts of all kinds keeping an eye out for characters you love and monologues you want to develop
- Since you like making people laugh, work up your own stand-up comedy routine to perform at school or talent shows
- Get together with friends and do your own shows for fun
For now focus on learning and growing as an actor and performer. Making people laugh is a wonderful talent to have - but it doesn't always mean you'll be a good actor (or that you will even enjoy the work of acting). But you certainly should give it a try!
More professional acting is a business - and very challenging. After you get some acting training and experience you and your parents can research what is really involved in attempting an acting career. It's not what most people think. A helpful website to get you started:
