Professionalism- How Do You Work?

I watched a forensic pathologist at his job on tv, And found him unbelievable charming. He was unfazed nor distracted at any time during his examination. Not even interested in power play or environmental pressure, But did his work steadily at ease, trusting his own intuition, experiences and skills set. He is purely evidently professional. How should one continue hoping; if it's just super low probability of 1% of the real deal good case apart from the 99% done deal?
