I still remember working with the first client who didn't see eye to eye with me on what the final design we were working on would look like. I wasn't freelancing—it was a studio job, and I didn't have much choice in working with them. All I could recall was vowing to “train” my clients moving forward to spare myself the frustration. A few failed attempts later, and I learned that clients aren't puppies. You can't train them like one.
