"Les gens n'apprennent jamais rien en se faisant dire, ils doivent découvrir par eux-mêmes."

Simplified Meaning:

When we simply tell someone something, it doesn't always stick because they haven't experienced it themselves. Think about the first time you tried to ride a bike. Someone might explain how to balance and pedal, but you won't really know how to do it until you actually try and maybe fall a couple of times. Those falls teach you what not to do, and that's how you really learn. In real life, it's much the same. Imagine your friend always stays up late and feels tired the next day. You advise them to go to bed earlier, but they keep staying up late. Only when they experience the tiredness and struggle through the day will they understand why early sleep is important. So, if you want to truly learn something, you need to experience it firsthand. This might mean making mistakes or facing challenges, but these experiences help the lesson stick in your mind. Remember, real understanding comes from doing, not just hearing.
