They say that every season has its purpose. In nature, Autumn bring the falling of leaves which nourish the soil, that then feeds the tree from which the leaves fell. Summer provides lots of sunlight to help plant life to flourish, which helps all life to flourish.
You might feel like you are in a difficult situation that might be likened to the harshness of Winter, but difficulty can help us to develop resilience. If it was like the Summer all of the time then we may not appreciate what we have. Every year Winter shows us what the absence of Summer is like and we appreciate it all the more when it comes around again.
In life we have challenges and we have moments in the Sun. Each has its purpose and we can use them to our advantage, if our mindset is a growth mindset and we look for the opportunities rather than the difficulties.
