Sarah discussed the concept of breakthrough trees, using the example of a tree growing out of rocks in Southern California. She compared this tree to another in Minnesota, both of which were healthy and thriving despite being deliberately planted in challenging conditions. Sarah used these examples to illustrate the idea that sometimes, despite adversity, growth and success can still occur. She also touched on the notion of the grass always being greener on the other side, using it as an analogy to the trees' ability to break through obstacles.
