Self-pity can lead to anger. Feeling sorry for yourself is a waste of energy. It would be better to use this energy to facilitate change. The past cannot be rewritten no more than a large tree can become a sapling again. Regrets can be a tool to learn from, or they can be a heavy burden to carry. The tree that loses its leaves has no regrets, it is only a natural process. In spring, new leaves appear, new opportunities, new horizons.
