The distinctions of uncertainty are many:
Things that are unclear, unresearched, unconfirmed
Things that are unpredictable, variable, changeable
Things that are untried, untested
At the core of each category and example is the abundance of known unknowns (things we know we don't know) and unknown unknowns (things we don't know we don't know). When we engage unknowns as assets, we gain new knowns and new unknowns. The continous emergence of new unknowns is the pathway to experiencing what most interests us.
