This list from Inc. reminds me of  our many remarkable employees. In particular, these three resonate:

• From #7, “Education, intelligence, talent, and skill are important, but drive is critical. Remarkable employees are driven by something deeper and more personal than just the desire to do a good job.”
• From #6: “They speak when others won’t.”
• From #8: “Some people are rarely satisfied (I mean that in a good way) and are constantly tinkering with something: Reworking a timeline, adjusting a process, tweaking a workflow.”
