My husband went to see his mother for her 90th birthday. This woman is amazing. She rode roller coasters and traveled through her 80s. She always has another goal to meet, something else to do.
My mother has a friend whose family wanted to celebrate her 92nd birthday. The woman asked if they could hold off, because she wanted to get her vegetables canned and didn't have time to celebrate yet.
My mom still laughs about that, but she has an idea about all of this. The more you plan, the more fun you have, and the younger you feel. The more goals you make, the better. The more you do, the more you'll be able to do. My mom is 84 and going strong. She might have a pace maker, but you'd never know it from all she does. She never gives up, always moving, talking to others, and enjoying life.
When I was a kid, we'd visit my dad's Aunt Ruth. She'd have us all sit in a room, where there was no noise but the grandfather clock, ticking away the seconds. The woman was waiting for death, or so it seemed. Back then, it seemed like people over 60 were old and decrepit. They gave up. But nowadays, it seems as if people in their 80s are still going strong, for the most part.
So the next time you give up, think about this. When you run out of goals (or stories, in a writer's case), find another goal to strive for. Always look forward to the next roller coaster, or the next birthday. It'll keep you young.
It also makes for great characters to write about older people still full of life.
Have a great day!
