Do something unpredictable. What could you do that would completely surprise the people who know you? Wear high heels? Skydive? Take a dance class? Bold people aren’t afraid of trying new things, and one of the reasons they’re so exciting to be around is that they keep you guessing. You can start small, perhaps by wearing a color or style of clothing that you don’t normally wear, or visiting a place you normally wouldn’t visit. Eventually, you may get to the point where you entertain ideas that make other people’s eyes widen when you mention them (“Are you serious? White water rafting?” or “You’re kidding me. You want to buy that restaurant on 3rd Street?”).
