"なぜ悪いとされるもの全てが私をこんなにも良く感じさせるのか"

Simplified Meaning:

This quote is about a common experience where things that are usually considered harmful or unhealthy often feel enjoyable or satisfying. For example, eating a lot of junk food like chocolate and chips can be really fun and tasty, even though we know it's not good for our bodies. Similarly, staying up late watching movies feels exciting, but it can make us tired and unproductive the next day. People sometimes find thrill and pleasure in activities that aren't the best for their health or well-being because these activities can be fun or provide a temporary escape from stress. To apply this idea in everyday life, one should try to find a balance between enjoying these pleasures and not letting them become harmful habits. For instance, it's okay to have a slice of cake once in a while, but it's important to also eat healthy most of the time. This balance helps us enjoy life while taking care of ourselves in the long run.
