Do I still lie?
Do I still lie - yes, do I make a habit of it, no. Dishonesty and lying are not only nasty habits to break, they are defects of character and they must be broken if we are to once again regain the trust and respect of our peers. Is there a necessary lie? Maybe, but the instances are so few and far between that telling any lie for any justification decreases my spiritual condition as well as my human condition.
Telling the truth is so much easier to remember.
If dishonesty is a continuing issue, why not inventory your honesty and dishonesty on a sheet of paper at night? It takes but minutes to recollect the day's affairs and could save you much in the way of shame, guilt and remorse.
Honesty is still the best policy for me.
