"One falls to the ground in trying to sit on two stools"

This quote by Francois Rabelais is a metaphor for the trouble of attempting to do 2 things at the same time. It suggests that when somebody attempts to do two things at the same time, they will inevitably fail. This is due to the fact that it is difficult to balance on 2 stools at the exact same time, and so one will undoubtedly be up to the ground. The quote is a caution versus trying to do excessive at the same time, as it is impossible to be successful in both undertakings. It is much better to focus on one job at a time and do it well, rather than trying to do 2 things at once and failing at both. This quote is a pointer to prioritize and focus on one job at a time in order to be successful.
