Virtue #4 is Acceptance: To consider circumstances, especially those that cannot be changed, as satisfactory.
I won't write a negative list of "problems" that I have yet to accept as things I am not in control of. I am simply going to say, life is full of ups and downs. I fear that if we do not learn to accept some of those downs we may never feel successful, inspired, or clear-minded.
I am learning to refine my edges, part of that to me is learning to balance. Learning when to accept "defeat" and when to keep pushing for "more". What I do know is that there is an art to balance, we cannot always accept what we are given but we also must be aware that we cannot always control it either.
Start your practice soon, before you forget!
