For me nervousness was an understatement.  It’s normal to feel overwhelmed.  I burned chili, ruined my first batch of dogs because I had the heat up too high, didn’t lock my umbrella in and a little breeze took it for a ride (and chip clips attached to it), dropped a few dogs and the list goes on.  I did sell out of about 100 dogs, all of my water and Gatorade and chips.  This was at my local farmers market.  After that I reviewed the day in my head and told myself “hey, whats the big deal?”.  Mistakes may happen but if you remain calm and cool you’ll get by and soon build confidence to handle minor disasters.  Just believe in your abilities and learn from your mistakes.  Review your successes as well, figure out how to make the good things even better.  Good Luck !!!    DD
