Jason Rochelle Markov, I disagree! Preparing for a meeting is never a waste of time!  It is practice and practice is never a waste of time! I am not saying you are completely wrong, I am saying you are possibly looking AT it wrong.  I have turned a cancelled meeting into a new contact and a "practice" presentation which led to a new client!  Positive thinking means so much to your business!  I know you have a lot to offer; let everyone around you know it! ;)
