Many people, by my observation, approach their work by doing what is asked of them. It makes sense, isn't that what a good worker does? I think it's a wasted opportunity.
Never tell a man how to do something. Tell him what to do and let him surprise you with his ingenuity. --George Patton
I think we focus on the tasks and forget about the goal. I've done my best work when I've forgotten about the task and focused on the goal. I think that more organizations would benefit from focusing on goals and seeing tasks, not as inflexible plans, but as available paths to achieve the goals.
