Being optimistic about life is one of the hardest things you'll ever have to do, especially when things just don't seem to be getting better for you. whenever you think your done and finally experiencing some peace of mind, something else comes up and puts you at the edge again, a lot of us can relate to this.
but seeing life positively and making optimism a way of life, filtering situations optimistically and not letting negative situations fully beat you down is very beneficial and somehow will give you a head start in dealing with most of your problems.
nothing great is ever achieved easily, but if we all just hang in there and believe that our time is coming surely all our efforts will pay off. like i always say, "we have the greatest influence over our lives" and nothing should ever substitute that!
