Interesting concept....yet one must act as if they do "know" in order to make daily decisions....I assume you have a job and responsibilities that force decisions based on "what you know" at that moment...."knowing" is an accumulation of our past experiences so inside we "know" something based on that reality as we see it....

I get the part of "acceptance" and detaching from outside stuff that really doesn't impact us....does provide a point of serenity as one weeds out what is truly our stuff vs others....also the concept of "focusing on myself' helps me to stay on that path....

I would end with the reality of what you do know....you know you don't know...thanks for your thoughts.
