That's a beautiful reflection on the interplay of light and dark in art and in life. The contrast between light and dark, happiness and sadness, allows us to appreciate and understand the value of each. It's true that experiencing sadness can help us recognize and cherish the good times when they come. Life is a mix of different emotions and experiences, and it's in embracing the balance between them that we can find meaning and growth. May the good times you're waiting for arrive soon.
