I first encountered this quotation by George Bernard Shaw in Michael J. Fox's autobiography, 'Lucky Man'. In it Fox says he wants to live his life, now encumbered with Parkinson's disease, without self-pity and without making the lives of those around him miserable with his grievances. He uses what strength he has to raise awareness and money about and for Parkinson's disease and has succeeded admirably in those efforts. I enjoyed his book and think he leads an exemplary life - and it seems, one filled with joy.
I love Shaw's turn of phrase about avoiding being a "feverish, selfish little clod of ailments and grievances.......". It often comes to mind when I am about to share a list of current complaints.......and I try to pull back the impulse - and when I succeed feel much better for it!
