Sometimes you have to be flexible. Dealing with other people, in your car, maybe at home…
Also on stage, you have to be flexible, meaning things sometimes don’t work out as you hoped for. Most of the time you adjust, and everything will work out.
Even if you have an excellent Digital Presentation. Just have in mind. If the projector is not working I will tell my highlights in ten minutes. Believe me, this can be your best performance, mostly because you were prepared.
