When work doesn't go my way

I have a new work strategy to help me sell the best I can while I'm here in Cali. On days that I go out and don't sell anything, I force myself to go to the local gas station and get the biggest drink available and drink all of it on the drive home. It's sort of my punishment for not performing well. In most cases, the cup size is ridiculously huge (64 oz.) and ends up weighing about 5 pounds when full. I know one day I'll go in to a gas station and the biggest cup is going to be some kind of bucket thing...and I'll have to get it, and I'll have to drink ALL of it too. Hopefully I don't have any more "no sale" days.
