The tree in my backyard taught me to hang on, endure the bad times & bad weather bravely. Nothing in the world is everlasting, one day the sun will shine and seasons of blossom will come.
I remember a shloka in Bhagwad Gita where lord krishna tells arjuna:
(~ Bhagwat Gita Chapter 2 Verse 14 )
O Arjuna, only the interactions of the senses with sense objects result in cold, heat, pleasure and pain. These things appear and disappear, none of them are eternal, therefore endure them bravely.
