An important lesson I learned when I was young and working at WinDixie is to never get so comfortable in your work that you lose the desire to grow. I had cake-decorating tasks delegated to me by the lead decorator often. She was aware of her skill but was stagnant growth-wise. I spent so much of my free time watching videos and educating myself on the craft, that eventually I surpassed her as far as knowledge of newer/more elaborate techniques went. I remember that experience because it is what taught me to constantly try to improve.
