I will use myself as an example. I began my career as a graphic designer and built a skillset which was made up of learning design software, the basics of design principles, color theory and so on. Eventually I kept building those skills and worked my way up the list of job titles to Art Director. I could have kept going along that path, but the road gets much more narrow at that point. The positions above me that are left to strive for didn't seem fulfilling anymore. I began to question how I was really improving in my career outside of what's on my business card. So I took a step back to view the full picture of what it is that I do for a living.
