Years ago I participated in a NO challenge. I think the goal was to get at least 50 No's to a question like "would you book a party" or perhaps "would you like to know more about the SU! opportunity"? It gets you acclimated to getting rejected and you occasionally will get a "Yes". Maybe one yes for every no? I think a No jar is a jar to hold slips of paper to keep track of all the No's. You could decorate the jar to help inspire you to get more No's.
