"Il y a une raison pour laquelle le pare-brise est beaucoup plus grand que le rétroviseur."

Simplified Meaning:

When you're driving a car, the windshield is the large glass window in front that lets you see where you're going. The rearview mirror, on the other hand, is much smaller and lets you see what's behind you. This design is important because it's more important to focus on what lies ahead than what's in the past. In life, this means we should pay more attention to our future than to what's already happened. For example, if you made a mistake at school or work, it’s useful to learn from it, but you shouldn't spend too much time worrying about it. Like the windshield, we should focus on our future goals and opportunities. This helps us move forward and grow, instead of being stuck in past regrets. To apply this idea in your life, whenever you're faced with challenges or mistakes, acknowledge them, learn from them, and then refocus on what you can do next. This way, you can keep moving forward and improving your situation.
