" Effort is the unconstrained willingness to persevere through difficulty. It is not a harsh, straining, desperate effort but, rather, an ardent and wholehearted remembrance of our capacity for freedom. Right Effort is willingness to open where we have been closed, to come close to what we have avoided, to be patient with ourselves, and to let go of our preconceptions. "
