英文小作文：

标题：Fall Back on My Roots

As the leaves fall from the trees and the days grow shorter, I find myself reflecting on my past and my roots. I remember my childhood days, playing in the fields with my siblings and laughing with my family around the fireplace. I recall the warmth and security that came from being surrounded by family and friends.

Now, as I fall back on my roots, I realize that I am stronger than I ever was before. I am not afraid of falling behind or falling short of my goals because I know that I have the strength to rise up and overcome any challenge that comes my way.

I am reminded of the importance of family and friends, and how they can help me through any difficult times. I am reminded of the beauty of nature and how it can inspire me to appreciate the simple things in life. And I am reminded of the resilience of the human spirit, which can overcome any obstacle if we have the courage to fall back on our roots and believe in ourselves.
