Regarding creative work, I hear the following term a lot: Creating something from nothing.
A musician has the silence, and fills it with sound waves. A painter has an empty canvas, and fills it with paint. A programmer has a problem, and creates a solution. It can be challenging at first to grasp, but the initial state is not nothing and we're not creating anything. We are only transforming materials. This might be easier explained if we observe other crafts like carpentry or metalwork. Carpenters and blacksmiths create solutions to their customers' problems by crafting furniture and forging weapons amongst many other things. So why do we sense a big distinction between the so called "creative" work from "physical" work? I'll share a little secret: given that each person we observe in each field is a professional, the only difference in their way of working is the materials they use.
