Trust needs countless signals. It needs to be reinforced to stay intact, because it fades over time.
Mistrust only needs one signal. It doesn’t need to be reinforced, because it grows stronger over time.
The only thing that helps trust is people who forget, because they lack self-confidence, principles, pain, or the absence of alternatives.
And then there are the people who don’t forget, because there is enough self-confidence, principles, pain, or alternatives.
It’s a slippery slope, trust. So treat it with care.
Be generous with signaling what you are going to do and, act accordingly. From my personal experience I know the latter one requires the most attention.
