One of my favorite authors, Seth Godin, has a short lecture called Leap First.
At the 25 minute mark, there is a distinct humming noise in the background. Going back, you can hear someone vacuuming in the background during his lecture.
You got to think that he is in front of a live audience, being recorded, and now you have a vacuum creating a distraction. For most of us, it can throw our game. But it didn’t phase him. He didn’t miss a beat.
Because he is a professional. He is someone who steps up and does what he does best despite the distractions. Amateurs blame the vacuum for not doing their best work.
