"Sans la capacité de dire non les êtres humains ne peuvent pas dire oui"

Simplified Meaning:

Imagine you have a friend who always agrees to help others, even when they are really tired or have too much to do. They never say no because they don't want to upset anyone. Over time, they feel overwhelmed and unhappy because they aren’t taking care of their own needs. If this friend learns to say no sometimes, they can make sure they have enough time and energy for things that truly matter to them. They can then say yes to opportunities and commitments that make them happy and fulfilled. In other words, by setting boundaries and prioritizing, they can make positive choices that improve their life. This balance helps them feel in control and satisfied. Basically, saying no when necessary gives people the power to choose meaningful yeses. It encourages a happier, more balanced life where decisions are made with intention and care.
