I can think of countless business situations where I wish I could roll back the clock and handle things differently.  Someone puts me on the spot about prices or scope of work.  Wanting to please, sound intelligent, appear like I had my sh!& together, or whatever energy I was trying to give off...I've often spoken too soon.  Sometimes I've overreacted.  Sometimes I played the wrong hand.  Many times I overpromised myself right out of a profit.  It happens.  Live and learn.

I recently found myself in a situation that had me dealing with someone that had no business in the conversation, let alone room.  Someone who was trying to flex on ignorance vs knowledge.  Someone who was trying to handle me like they understood the playing field. It was a draining conversation.  My ego was on the ready. But I never lost my cool.  I held solid.  Even while they reduced themself to attacking my rates and the value I continue to bring to the table when they couldn't get their way.

But I just let them think they won.  Allowed them to feel accomplished when they told me they were going to shop my rate.  Even answered when they asked me how they should approach the competitor they were looking to replace me with.  

People are a trip, but you can't allow them to take you on one.  Just take a beat and let them realize who the fool in the conversation really is.  Because when you don't take a moment to pause before overreacting, to remember who you are and what you bring, that fool might wind up being you.
