Think first about the possible results of what you do/say. Think WORST CASE just in case then decide if it's worth it. If whatever "it" is could be embarrassing to you then DON'T DO IT. How hard is that to understand?
Obviously all the pols caught red-handed doing what they should not have done are perfect examples of what happens when you don't THINK FIRST. Why does politics attract so many with tawdry embarrassing pasts whose thinking apparatus does not function in their own best self-interest? Peculiar oddballs or odd peculiarballs or both.
