For when life seems unfair, we become resentful or complaining, bitter or dissatisfied; easily bearing grudges and unthankful.
Forgiving and accepting. Optimistic and full of gratitude.
‘For those who have suffered adversity or misfortune and find these difficult to accept, without complaint or resentment, as they judge life much by the success which it brings. They feel that they have not deserved so great a trial, that it was unjust, and they become embittered. They often take less interest and less activity in those things of life which they had previously enjoyed.’
