This old fable talks about a person who walks by a worksite and observes 3 workers moving boulders. The person stops and questions each of the workers for an understanding of what they are doing. The first worker replies that they are moving rocks. The second person says that they are building walls. The third worker proclaims that they are building a big castle!

Similar to the boulder fable, in the famous speech in front of the US Congress on May 25, 1961, President Kennedy proposed to the people of the United States of America that, “this Nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth.” The country rallied behind this ambitious goal and prevailed.
The key take away from these two tales is that, with support from a dynamic team, an individual can determine how high they want to reach; whether it is a moonshot or lower. It is all about the desire to dream big and the ability to execute. Correspondingly, a founding team can set a lofty goal and achieve it by having the whole team believe in the dream and committing to achieving it.
