Courteous. Trusting. Good-natured. Cooperative. Tolerant.
These are the traits your mother told you -- repeatedly -- to embrace. "They'll make people like you." "You'll always have friends." "You'll go far."

My colleagues and I studied the careers of more than 1,500 people over a 20-year period. Sorry, Mom, we found that being too nice won't boost you up the corporate ladder.
