Stoicism is an ancient Greek school of philosophy founded in Athens by Zeno of Citium in the early 3rd century BC. The philosophy has been popularized within entrepreneurship in the last ten years, and many prominent figures now use it as their personal operating system. Stoicism emphasizes personal virtue and wisdom, it teaches self-control and fortitude, it promotes rationality and restraint. These are not qualities ordinarily associated with entrepreneurs, who you probably know can be irrational, impulsive and hot-headed at times.
