"Il est plus sain dans tous les cas d'écrire pour les adultes que deviendront nos enfants plutôt que pour les enfants que sont souvent nos critiques "matures"."

Simplified Meaning:

It's better to create things that will help and inspire the grown-ups our children will become in the future, rather than trying to please adults who act immaturely. Imagine you're a writer or a creator. If you focus on making stories, art, or anything else that will help kids grow into smart, thoughtful adults, you're doing something valuable for the future. On the other hand, if you only worry about what critics think – critics who might be acting childish or just looking for faults – you might miss the chance to make a real difference. Think about a teacher who tries to inspire their students to think big and dream for their future, instead of focusing on impressing other teachers who might be stuck in their ways. By investing in the growth and well-being of children, you're helping shape a better, more thoughtful, and mature future. So, aim to make a positive impact on those growing up rather than seeking approval from those who may not appreciate it.
