It is better to be completely honest or completely dishonest. Being “just a little” dishonest is a problem.
Being just a little honest/kind/environmentally conscious means we are only those things when the situation suits us. The moment the going gets hard, we change our behavior.
The problem here isn’t just the unpredictability of our behavior – though that is definitely a problem. The bigger problem here is that we live a life built on lies to ourselves. We just rationalize away any bad behavior and think of ourselves as honest human beings. We do so by blaming all of our “just a little” behavior on extenuating circumstances. And, by gradually believing this lie, we stop feeling the kind of guilt that focuses us to take action.
The “Just a little” way of life is a massive problem because it is built on bad behavior during extenuating circumstances. Life, it turns out, is just a series of extenuating circumstances.
