Zig Ziglar is quoted as saying, "Your attitude, not your aptitude will determine your altitude!" I've only heard that used in reference to careers, but the truth is, it applies to everything we do in life, including aging.
I feel very fortunate to be surrounded by people with amazing attitudes at all ages and sometimes the oldest ones are really the youngest!
"People tell me I look good these days. I look good because I feel good. I know people who are older than I am who are twenty-five... It's all about attitude. To me, age is just a number."
