One of the top inspirational quotes, according to BrainyQuote.com, is "The best and most beautiful things in the world cannot be seen or even touched; they must be felt with the heart," which was said by Helen Keller. Another one, said by William Shakespeare, is "We know what we are but know not what we may be."
The Helen Keller quote is said to have come from her book "The Story of My Life," at least in part, according to QuoteInvestigator.com. The idea came from Keller's teacher, Anne Sullivan, who taught the blind and deaf Keller to read and write.
Shakespeare's quote comes from his play, "Hamlet." It is said by Ophelia in act 4, scene 5. She is speaking to Claudius and is referencing the story about the baker's daughter who was turned into an owl when she refused to eat Jesus' bread, according to SparkNotes.com.
Another popular inspirational quote is, “I can’t change the direction of the wind, but I can adjust my sails to always reach my destination.” This quote from Jimmy Dean is interpreted by MadeMan.com as meaning that people need to be flexible. People do not always get to their destinations when and how they want, but if they give it time, getting there is sure to happen.
