"Youth comes but once in a lifetime"

This quote by Henry Wadsworth Longfellow speaks to the short lived nature of youth. It is a tip that youth is a valuable and limited resource, and that it should be cherished and delighted in while it lasts. The quote suggests that youth is a time of life that ought to be taken advantage of, as it will not return. It is a pointer to take advantage of the opportunities that include youth, as it is a time of life that is full of possible and possibility. The quote also works as a cautioning to not take youth for approved, as it will not last permanently. It is a suggestion to maximize the time we have while we are young, as it is a time of life that will never ever return.
