What feels similar is the pursuit — by artists and entrepreneurs — of the actualization of an idea borne in their minds; and then pursuing bringing this vision to reality. Especially at the beginning, it takes just the right amount of delusion to dedicate yourself to something ambitious. The reality is you’re more likely to fail than succeed and so you need strong belief to commit your heart and soul to an idea; as well as a bit of over-optimism (delusion) to make the sacrifices they are often called for to bring anything to life.
