Imagine a bubble show artist giving the same old program day after day, this will not bring him/her any inspiration or joy. Therefore, I constantly try something, check it out, introduce one new trick at a time, see how the audience reacts to it. During my interactive parts, I constantly improvise, interpret my tricks differently. Looking at the reaction of people, you can understand what they like, which trick is more effective, and which one is better not to repeat.
