Quote

Life can only be understood backwards; but it must be lived forwards

Nothing is a waste of time if you use the experience wisely

There is nothing so easy to learn as experience and nothing so hard to apply

Life is like playing a violin solo in public and learning the instrument as one goes on

A mind that is stretched by a new experience can never go back to its old dimensions

All experience is an arch wherethrough gleams that untravelled world whose margin fades for ever and for ever when I move
