Don't know what brought it on but today was my busiest in a long time. I even had to turn one down as could not do the time he wanted, I was already booked. No real reason I know, just the way it goes. After my last one I was glad there were no more, one thing for sure I would not want this busy a day every day, no matter how much money.
Pacing myself has always been the way and I think that is why I have not experienced burn out.
