The complete honesty with yourself seems to be one of the key ways to live a good life. And honesty with others when they ask for it or when not being honest could have an unwanted effect on their life could be just as important and just as valuable in living the best life that you can. Ditto for telling white lies.
And being honest with others helps them deal with the situation earlier, and make a decision based entirely on what is the truth of the situation, of what you say, what you think or what you want. And also helps you live a life of freedom – freedom from deceiving yourself and others, even in little ways.
