Business and the challenge of letting go

One of my biggest frustrations in the boothing business is when someone sends us an inquiry but then never responds to our emails. I get the inquiry and am excited about the potential booking.  I send over the proposal knowing we can make the event awesome.  Then I hear nothing........  So I send over a follow up email.  Nothing......  So I send another email and another and another.  Crickets......  Why won't they respond??  They contacted me and I was a good business owner and responded right away.  What am I doing wrong?  The answer is probably nothing.  However, the bigger issue was revealed to me last night as I read Donald Miller's book "Storybrand."  In the book Miller says "the day we stop losing sleep over the success of our business and start losing sleep over the success of our customers is the day our business will start growing again."  Its an easy mistake to make especially since its been a slower than normal year for us.  My desire to grow my business became more important than my desire to serve the client.  When that happens every unanswered email and "lost" client increases my anxiety and frustration.  In reality if a potential client doesn't want to email me back, do I really want them as a client?  Probably not.  This is a good reminder that all I can do is put my best foot forward and let go of the results. For me putting my best foot forward means slowing down and learning more about what the client really wants.  Self evaluation is great, but for me it can turn into that voice that says "you're not good enough."  In that moment I need to remember the truth and LET IT GO.  In the meantime, email me back damnit!!!!!!
