For people working in the public eye, but also in most other cases, all of the above won't do much good, unless they are articulate enough to explain their views. It should be easier to explain reasoned views, and measured decisions, but in all too many cases the glib declarations from public relations people seem more convincing to the world. This is frustrating, and can lead someone to give up. But our hero, the role model of integrity, never gives up. This is only the beginning.
Life makes things much harder, and provides very nasty obstacles.
People threating your kids, conflicting goals, and fuzzy complicated issues. Some judges have to face such a terrible life every day. Some even do their jobs with integrity. You really have to value the things you believe in, in order to stand the pressure. To some people, it is a sense of duty.
