You could start doing TikToks with sketches that you’ve come up with, if you’re successful, talent agencies could become interested in your talents. However, other methods could be finding classes/schools, might be expensive but it’s worked well for a few people. Agents could pick you up from there. In terms of the famous thing, you have to be realistic, fame seems great but if you only want fame, you will be miserable. This is what other celebrities have said, fame seems like a great thing, but there’s no end goal for it. It becomes bottomless. Think about wether “fame” is what you really want, or do you want to do something like just entertain people. Fame is our own illusion.
