"L'avenir n'est pas plus incertain que le présent."

Simplified Meaning:

Life is always unpredictable, whether we are thinking about tomorrow or dealing with today. Just like we can’t be sure about what will happen in a week, we also can't be completely certain about what might happen in the next few minutes. For example, think about the weather – we can check the forecast, but sometimes it still surprises us with rain on a sunny day. This means that worrying too much about the future doesn’t make sense because right now is just as unpredictable. Instead of being anxious about what’s to come, it's better to focus on what we can do now and enjoy the present. By living in the moment and taking things as they come, we can feel more at ease and prepared for whatever comes our way.
