"What is a weed? A plant whose virtues have never been discovered"

This quote by Ralph Waldo Emerson is a suggestion that we need to not be so fast to judge something as being useless or unimportant. He is recommending that we should make the effort to look closer at things that we may take into consideration to be a problem or a weed. He is suggesting that we need to not be so quick to reject something as being ineffective, as it might have merits that we have yet to uncover. He is motivating us to take the time to discover as well as value the charm and also possibility of all points, also those that we might consider to be weeds. He is advising us that we should not be so fast to judge something as being useless, as it might have merits that we have yet to discover. He is recommending that we ought to put in the time to look closer at things that we may consider to be a nuisance or a weed, and to appreciate the appeal and also possibility of all things.
