It is not a wise career move to cancel. Cancel on canceling when possible is what you should do. It is your business to accomplish things be it a schedule a meetings or a performance. I know sometimes its fun to cancel things. Don’t do it though it makes you look dimwitted and slow. OK maybe not, but it does make you look like an unprofessional slacker so avoid canceling things.
Canceling is a really, really awful idea. Not showing up is a bad plan, bad, bad VERY BAD! Especially for you! Ya you the one on the left trying to figure out why a screen door on a submarine is a bad plan. Just saying. Look canceling on a show is not good, chances of you being put on with whoever set it up again isn’t good. The venue owner is going to be pretty ticked off and overall you will have a really bad day at that point. You just cut off your nose to spite your face, you the baby out with the bathwater and finally you made yourself look like an amateur. That is definitely not the goal right? Amateur hour is the line to your right, go get on that line if you want. Comes with a paper hat and a name tag.
If something truly awful happens you still don’t cancel get someone else to cover it for you call another comic or a band or someone to try and get them in to the show for you. Then call the place and tell them you can’t be there, and that whoever it is you have covering will. Give them the replacements info so they can contact them and then deal with whatever life crisis has struck you.
That’s it folks, now no more cancellations. Use your networking to give yourself some back up at all times. Remember you owe people to be there when you say you will and you owe yourself.
