____

    Although you may often stay silent if something is wrong or bothers you, it is better to speak your mind right away. You don't have to be rude, but you do have to be firm and direct.

    Judge well.

    When dealing with others, you have to exercise good judgment. ____If a colleague isn't doing his part, you should rightfully demand that he start doing so. However, if a taxi cuts you off in traffic, just let it go.
