We trust realistic expectations. We trust others who have realistic expectations. We mistrust unrealistic expectations and those who have them.
In the growth realm, realistic expectations have to do with progress. Progress is by definition actionable. It only requires what goodness, resources and opportunities we already have. Making progress releases the motivation chemical of dopamine in our brain, which energizes us for continued clarity and momentum.
Progress is possible in aspect of growth, individually and together as teams.
Progress is in no way short view focused. Our best progress is inspired by our longest view definitions of the good we seek.
