“This too shall pass.” – Anon
This possible came from the Sufi poets but nobody really knows for sure and it doesn't really matter.
The way of life is change. Good times come and good times go. Bad times come and bad times go. If we can remain relaxed in the knowledge that we'll deal with the change that comes our way, so much the better. If you are going through tough times at the moment, know that they won't go on forever.
