"只要这一切存在，只要有这灿烂的阳光和这万里无云的天空，只要我还能享受这一切，我怎么会难过呢？"

Simplified Meaning:

When you have something beautiful and good in your life, like a sunny day with a clear sky, it can make you feel happy and positive. The idea is that even if other things aren’t perfect, you can find joy in simple pleasures around you. Imagine walking in a park on a bright sunny day, feeling the warmth of the sun on your face, and seeing the blue sky without any clouds – it’s hard to feel unhappy in that moment. Think about someone who might be going through a tough time but decides to spend time outside, enjoying the weather. The beauty of nature and the peaceful feeling it brings can lift their spirits, making it easier to handle problems. This quote suggests that by focusing on these small, happy moments, you can keep sadness at bay. In our everyday lives, we might face challenges at work or school, but taking a break to enjoy a sunny day, a beautiful garden, or even a nice cup of coffee can help us feel better and more positive. By appreciating the good things, no matter how small, we can find happiness and stay strong even during difficult times.
