This is a geometric representation of our everyday life. Our everyday life is almost the same, but then there are some changes like... we start walking, we start talking, we see a death in the family, we fall in love, break ups and so on. On that particular day, it has a small effect on the shape of the day. But slowly these small changes create a pattern and shape our personality. So we don't remain exactly how we were as a child.
This phenomenon is very much a part of geometry too, especially in the cases of recursive functions and wave equations.
Every line represents a moment in our lives.
It may seem inconsequential but it is contributing to a larger and meaningful pattern.
Essentially, every moment has meaning.
Even if the moment is mundane or unbearable, it is contributing to a larger pattern.
