There's nothing anyone but yourself can do about "[...] a person's perception of herself and what people might be thinking, not the way others are acting."

Agreed. On the other hand, for a person thinking negatively about himself or herself, the absence of feedback will often be interpreted as negative feedback.

Being nice to our colleagues (male or female or other minority group) and giving positive feedback when it's appropriate tends to increase a team's overall morale and productivity.

Absolutely. On a related note, we seem to be a lot better and consistent at giving negative feedback. Encouraging positive feedback and giving more of it to young people as they grow up would probably go a long way.
