There are so many things school doesn’t teach. School will not teach you how to handle that erratic client. It will more often than not teach you about academics on how to do the task and not how to handle the task.
School of academics will only mention of having emotional intelligence as a virtue but will not show you how exactly to cultivate it. The school of life will make you cultivate it.
Most creatives do not know how to handle clients; how to tickle them, how to present themselves, how to negotiate on pricing and how to win over deals. Well, this is the class to teach you that.
