"人们可以有许多不同种类的快乐，但真正的快乐是他们愿意为之舍弃其他快乐的那种。"

Simplified Meaning:

Everyone enjoys different things in life, but there's usually one thing that makes them happiest. For example, think of someone who loves playing sports, watching movies, and hanging out with friends. If they had to choose just one activity to do for the rest of their life, they would pick the one that makes them feel the best inside. Imagine a person who likes reading books, listening to music, and cooking. If cooking is what truly brings them joy, they might skip reading and music just to spend more time in the kitchen. This tells us that real happiness comes from that one special thing we value above everything else. It's important to figure out what that is because it can guide our choices and make our lives fuller. So, if you find that painting makes you happier than anything else, focus more on that because it's likely your true passion.
