You already know this, but just a reminder: Nothing baffles people full of tricks and duplicities more than simple straightforward integrity.
For example, if you have pledged against texting or talking on your cell phone while driving, also refrain from doing these similarly distracting things behind the wheel: scratching off a lottery ticket, reading the Bible, eating a bowl of cereal, changing your clothes, or painting your fingernails—despite the fact that those activities (all of which I've seen people actually do) are not stated in any anti-texting pledge or law.
The far end of lacking integrity is breaking the law. There are corporate scoundrels who are involved in insider stock trading, securities fraud, wire fraud, money laundering, bribes, Ponzi schemes, and kickbacks (just a short list of potential options). People steal, cheat, and lie online and off. Experts report that today cybercrime is more prevalent than drug crime.
In this day and age, you will be found out. You might go to jail. You will lose trust from family and friends, and you will never get it back—even when you are being truthful.
Integrity is pretty simple: show up, get in fast with the truth, let go of the outcome.
