It was very appropriate that the picture shown on September 1 / 2 shows feet - as in time marches on.
The quote for that calendar page says:
Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.
Samuel Ullman - German poet (1840-1924)
That is also so appropriate for the challenge of time.
PS I just went and looked up the whole poem, which I have never read before, and have discovered my new favourite poem! Absolutely wonderful. Thanks :)
