Hard to disagree with the above quote really.. Anyone with hope or optimism for the future generally does not come to this way of being from observing the environment nor seeing a great future before them.. Most of the time optimism stems from within our own minds even when the odds are stacked far against our favour. Be realistic and pessimistic, but also allow yourself some optimism for life as you wish it to be.
