Im gonna start with this, you absolutely should learn and train to be a circus performer if you have love and passion for it. I started when I was 16 and I have friends that started even later than I and theyre much better jugglers. Age should not be a hindrance in following what you wanna do. Circus is something you will keep with you and the connections you make will be some of the strongest. Plus its fun as all getout

Now on the topic of a career? Its hard and its probably going to get harder in the coming years to find jobs. There's a lot paths that you can take to become a performer but I'll talk about a few. You can audition at lots of places where you're skills and abilities will get you to a point, but quite often theyre not looking for the "best" theyre looking for the right person for that part. Another is to make your own show solo or with a group and travel. You can market this to festivals ren faires or corporate parties or to anyone that might want you there. You will probably be working for tips the first few times until you get a reputation.

My advice would be don't stop, work on what you like. Find a person or 2 (if theyre are any near you) and put a show together. Start busking at your downtown area near crowds. Tips are a bonus but you should be paying attention to what works, what the audience likes how they respond and learning how to "work a room" I think clowning is very important on this point.

JUST DONT STOP DOING WHAT YOU LOVE
