"The only thing constant in life is change."
I like this aphorism by Heraclitus very much.
In the 1970's I was extremely busy working 14 to 16 hrs a day
yet made a rule to have lunch with an old widowed physician
around my age now 80 at the hospital doctor's dining room every Saturday.
He told me once, " Hahn, I find it most helpful to be flexible in life to survive.
Be always flexible."
I wasn't too impressed then. Indeed it sounded somewhat odd to me then.
Now I am at his age and understand what he was saying.
Not only that but also feel the truth of the phrase, "being flexible", every day.
Being flexible in life meant what Heraclitus said, I now believe.
So we need to learn to adapt ourselves to this constant change in life to survive.
Only the fittest survive according to Darwin's law, they say,
although that law doesn't always work in this Pandemic, but
very much apropos indeed.
