The advice below is from my friend, Bernie's mom, Kitty, who is well over 90 years and enjoying every minute:
When your back hurts, keep moving.
When your feet hurt, keep moving.
When you are dizzy and need a cane, grab it and keep moving.
If you are in a wheelchair, make the parts of your body that still work, keep moving.
A smile is so infectious that you can catch it like the flu. When someone smiles at me, I start smiling too.
This advice, gleaned from other wise people, is from Shelia, my younger sister's best friend:
Never be bullied into silence. Never allow yourself to be made a victim. Accept no one's definition of your life: Define yourself. Harevey Fierstein
Open your arms to change but don't let go of your values. The Dalai Lama
Though no one can go back and make a brand new start, anyone can start from now and make a brand new ending. Carl Bard
When the heart grieves over what it has lost, the spirit rejoices in what it has left. Sufi saying.
