"I would like to recapture that freshness of vision which is characteristic of extreme youth when all the world is new to it"

This quote by Henri Matisse speaks to the beauty of youth and the freshness of vision that features it. Matisse is suggesting that when we are young, the world is brand-new and amazing, and we have a special viewpoint on it. We are able to see the world with a sense of wonder and curiosity, and this is something that Matisse thinks deserves regaining. He is suggesting that we ought to strive to preserve this sense of freshness and openness to the world, even as we age. Matisse thinks that this is an important part of life, and that it can help us to value the charm of the world around us. He is motivating us to keep our minds open and to never ever lose sight of the charm of the world, no matter how old we get.
