What are the people and stories with good mentality?

The old lady has two daughters. The eldest daughter married an umbrella seller, and the second son-in-law made a living by selling straw hats. One sunny day, the old lady sighed and said, "The umbrella of the eldest son-in-law is not easy to sell, and the life of the eldest daughter is not easy." But when it rained, she remembered her second daughter again: "Nobody buys straw hats anymore." Therefore, whether it is sunny or rainy, the old lady is always unhappy.

A neighbor said to the old lady, "If you think about rainy days, the umbrella of the eldest daughter sells well, but if you think about sunny days, the straw hat business of the second daughter is good.". Aren't you happy every day? "

The old lady listens to her neighbor's words and wears a smile on her face every day.

In fact, if you look at anything from multiple angles, you will get different conclusions. Life is always full of contradictions. We should learn to change our thinking and find the source of happiness.
