Radical honesty is not about sharing everything on your mind. It is simply about being completely honest and refraining from lying, even from telling little white lies or making inaccurate statements. Honesty can sometimes be inconvenient, or even dangerous. In situations when you are tempted to bend the truth a bit, trust that, in the long term, choosing to be truthful will be worth it. Of course, in an extreme case where there’s a risk of physical danger to you or others, lying might still be a valid option.
It takes skill to tell the truth in a way that safeguards you and others. You might want to assess whether the other person wants to hear your truth, and whether the current setting is appropriate. Try to anticipate how what you say will affect them emotionally and adjust your delivery accordingly. You can also ask the other person in advance: “Can I be completely honest here? Is this a good time?”
A commitment to honesty doesn’t mean you must share everything on your mind with everybody. Helpful phrases to lean on when you don’t feel comfortable speaking the truth can be, “I don’t want to answer that question,” or, “that’s private.”
