There is a turning point that comes early or late in a person's life, where the clear realization comes in that a ferocious dedication to telling the truth is a path to sanity and personal freedom; and that the social machinery of falsification, in which we all have been trained, is a machine that breeds numbness of heart and mind.
'Course, there is a concomitant of courage required to do this, but my experience is that the "dangers of telling the truth" are actually much less than the amorphous fear that precedes doing so.
The other great thing about truth-telling is you do not have to remember what you said to whom.
