In the old town section of Barcelona, I was on a tour with my wife when I came across this opera singer who wanted to practice in front of a live audience. So she went to the busiest part of town and started practicing, started singing.
You can even hear me talking to my wife at the front of the video. She was afraid I was going to fall to far behind our tour (which is why I didn’t shoot a longer video).
We make the mistake of thinking we need ideal conditions to practice. We don’t. We just need to practice. Do it anywhere. Do it as often as possible. The more you practice in impossible conditions, the more you will make the impossible look easy in front of your audience in your next presentation.
