Choose an act. Circuses usually require auditions, and you should build a repertoire. Look into things like acrobatics, diabolo, unicycle, and trampolining. Once you’ve picked something to study, get equipment for it and begin practice. Build a bit of a show, perhaps with a theme for entertainment value, to attract possible employers and for use in auditions.

Find a good costume. Some performance attire can be revealing, tight-fitting, or simply wacky. Make sure you have the right costume for you, and that it fits your act. For example, you wouldn’t want long, flowing sleeves for fire dancing.

Make sure your makeup is pixel perfect. In the circus, you have to do everything yourself with no help from a makeup attendant. So purchase and collect your own makeup. Good things to use are shiny eyeshadow and diamond studs. If your show has a theme, play off of it. For example, a show based around fire might involve brightly colored makeup.

Practice your smile. Yours may vary based on your act and your own personality. Some performers may opt for a sexy, one-sided smile, but a friendly grin can also warm the hearts of your audience.

Consider the realities of circus life. The circus is a crowded environment by nature, and you may not have much time alone. If you can’t stand the thought, consider performing in another setting.

Turns out circus life [complete with clowns] is just like any other.

You have to pay attention.

Or you’ll fall off the trapeze.
