I found this article to be very true for me. Especially this part, "Every person who works in a creative field has an aspiration for her work, a yearning for that ideal plane which is the culmination of her taste. When an environment fails, over and over and over again, to provide her with a means to follow her internal compass, then she will leave. If you are in a position to influence that kind of environment, take heed. Lay the foundations for a space that nurtures, that yields the kind of work the best creative people can be proud of. Then, you will not need to ask why designers leave."
