"人生は心が思うほど深刻ではない。"

Simplified Meaning:

Sometimes, we overthink things and make problems seem bigger and scarier than they really are. Imagine you're preparing for a big test, and you start worrying that if you don't do well, your whole future is ruined. This makes you anxious and stressed. But in reality, one test is just a small part of your life. Even if you don't do well, you can study harder next time or find other ways to succeed. The quote is reminding us that our minds can blow things out of proportion. It advises us to relax a bit and not let our worries control us too much. Think about how children play and laugh without worrying about every little thing - that’s a good way to live sometimes. So next time you find yourself stressing over something, take a step back and remind yourself that it might not be as big a deal as it feels. It's important to find joy and not get too caught up in our own thoughts.
