A lot of productivity advice recommends figuring out what the most impactful tasks you have are, and focusing more of your energy on these. This is good advice, but how do I know what those tasks are? (Aside from asking my boss.) I do a variety of things: is it most important that I do them quickly, or that I do them well, or that I am pleasant to the people requesting them? How do I determine what my focus should be? Please recommend an exercise to help me figure out what the values are in my workplace so that I can strive for excellence. I really want to do well in this job.
