Security, Training, and Paranoia

"Be careful that you do not become so paranoid that you begin seeing ghosts around every corner and demons under every street light. Temper your paranoia with solid training, approach every relationship with the sure knowledge that while it may not fail there is a very real likelihood that the individuals you friend are not who they seem. A Russian proverb made popular in the United States says, “doveryai, no proveryai” or, trust, but verify."
