I enjoyed it, at times. And I made good money. But it was mostly frustrating as I found that the real interesting and fresh designs always found their way to the bottom of the pile, while some clueless CEO screamed for a bigger logo and more sparkly things. Over the years I've felt the creativity being sucked out of me...no amount of money is worth that.
Now, I know designers can get carried away, but 9 out of 10 times when you see that horribly oppressive website design with the asinine UI, it's often the brain-child of the executives and/or the marketing department.
Trust me, the Kangaroo knows what I'm talking about.
Anyhow, I enjoy doing design much more now that I'm doing it for myself and for fun (for others).
