Trusting or Gullible? Hard to differentiate. :)
For the first 40 years of my life MOST poor decisions on my part were from being TOO trustful. I tended to believe most people. Including Employers, the government, Watchtower and JW Elders. lol.
I like Ronald Regans use of the common Russian saying. "Trust but verify". "Trust, but verify (Russian: доверяй, но проверяй, romanized: doveryay, no proveryay, IPA: [dəvʲɪˈrʲæj no prəvʲɪˈrʲæj]) is a Russian proverb, which rhymes in Russian. The phrase became internationally known in English after Suzanne Massie, a scholar of Russian history, taught it to Ronald Reagan, then president of the United States, who used it on several occasions in the context of nuclear disarmament discussions with the Soviet Union."
