When did you feel that your business had become a success?

Hello everyone!

I thought it would be interesting to hear from members of the Community on when they felt that their business had become a success.  Perhaps it was the first customer, or maybe the 10,000th, that provided the achievement. Maybe it was a long journey, or a short one, before the moment arrived. 

Whatever the story may be, I hope you'll take a few moments to share it!  We all could use a bit of inspiration during this busy time of year.
