Quotations:

“The best time to plant a tree is twenty years ago. The second-best time is now.” — African Proverb

I love this perspective on carpe diem.

This text is often quoted as “Chinese proverb” but I was unable to find any connection to a real source.

On the other hand, I was able to trace the text to Dambisa Moyo’s book Dead Aid, where she attributes it to an African proverb.
