Ut est rerum omnium magister usus (roughly "experience is the teacher of all things" or more generally "experience is the best teacher") is a quote attributed to Julius Caesar in De Bello Civili, the war commentaries of the Civil War.[1][2] Since then the phrase has become a common saying regarding learning and leadership.[3]


John C. Maxwell stated that the only way of learning from personal experiences is to reflect on them, something he feels Caesar had done a lot of, which was the only way he was able to become successful and write down his thoughts.[4][5]
