Do something "Mildly" stupid on the internet. That's how many get famous. Or, You could actually try your best to succeed. Find your talents. And work around those. And hope someone notices those talents.
It all depends what you want to be famous for. If you have a talent for singing, sing. If you have a talent for dancing, dance. One of the only ways you can become famous is by advertising yourself on mainly any internet source such as Twitter, Facebook, Instagram, and especially Youtube. I wish you the best of luck with finding an idea and I hope your new career. Believe in yourself and anything is possible!
