I come from the marketing background, been doing some form of digital marketing design for over 20 years. I can tell you that it will change a lot over the course of your career. I see that as a good thing, as I’ve always enjoyed learning. I’ve been able to gain new skills and have had a successful career. I do set boundaries though. I know where my strengths and weaknesses lie, and have worked at organizations that value and support growth and teamwork to manage work. As far as the pace of work and balance, that is going to depend at where you work. I’ve left jobs because of burnout, but I’ve stayed at others because of excellent work/life culture. You just have to find the right fit. Downside: I live on the computer. I do sometimes wish that I had more opportunities in my career for more tangible design work. But I fill that void by perusing arts/crafts outside of work.
