.....the greatest teacher, and
when the lesson that needs to be learned is important enough, it hardly
matters whether that experience is positive or negative. When we look
back on all the events that seem to confirm our wisdom, we have to
wonder whether these have helped us or just conditioned us to remain
upon a path that is so straight and narrow that it offers no scope for
discovery.
Through looking at what has gone wrong in the past, you stand the best chance of making things right in the future.
Our best thoughts come from others (Ralph Waldo Emerson)
