"I am often over-ambitious and take on too much. I've learned to focus, complete one project at a time, and complete it very well, instead of doing a lot of projects but completing them superficially. Recently, I had the opportunity to lead several projects which were all very interesting and offered a chance to develop new skills. I was tempted to take them all on, but instead, picked the most interesting one and let the others go. I got a better learning experience by concentrating on one project and the result was better as well."
