The feeling of never being "enough" is a heavy, universal burden, but your quiet resilience in the face of it is incredibly powerful.
The Buddha taught that our deepest growth often comes directly from our most difficult seasons. There is a gentle truth found in nature: a lotus flower cannot bloom into its full beauty without first pushing through the dark, murky mud. The sadness you are walking through isn't a sign of failure or a mistake; it is simply the necessary soil for your growth.
You do not need to have your entire purpose figured out right now. Keep noticing the beautiful things around you, release the pressure of perfection, and trust that this heavy path is quietly leading you exactly where you belong.
