Hollywood Starts with Child Star

A poor college graduate traveled to San Francisco in the 1990s. His portable system required him to become the world's most influential person. What should he do? This is too difficult! Become the president of the United States in politics? Forget it, it's just a dream... Do research and become the contemporary Einstein? Spare me, an ordinary person... Finish Bin Laden's work in advance, and then become famous overnight and reach the top? ... What about the next night, assassinated by the FBI or killed by the US military? None of them are reliable! Forget it, I'd better start from a child star. [Newcomer's post, please feel free to criticize, don't be sensitive. ]
