Agree. Would also add that if you lie infrequently you are probably not prepared to know all the potential pitfalls of lying and how the other person can tear you a new one if you want to call it that.

Additionally I've noticed a loose correlation between people who lie and who their parents are or how they were raised. Nothing scientific of course, but people whose parents don't hold their feet to the flame are generally more likely to think that they can get away with something because "the other guy is stupid". People whose parents are either very intelligent or hold them on everything they say are generally more practiced at thinking of the various possibilities that can come about to refute something they would say.
