I'd advise against the "famous" part. Less than 1% of actors are famous celebrities. Thus, it's not an achievable goal.
And most of those that are famous didn't plan on becoming famous; it just happened by chance, for example, Jonny Depp, Ashton Kutcher, Mel Gibson, and Jennifer Lawrence, among others.
Additionally, some are gifted in extraordinary ways, e.g., Dwayne "the Rock" Johnson, while others did extraordinary things to become famous celebrities, such as Schwarzenegger.
Actors whose main goal is to be famous end up doing horrific things to become famous. Some of them end up in trouble.
I've seen some even plan murders just to become famous.
Just aspire to become a good actor, and if you're lucky, you'll become famous.
Trying to become a famous celebrity will make you desperate and could make you do horrific things in pursuit of fame.
