Having a positive attitude is always a plus when it comes to leaving an impression, getting to know new people, and keeping your chin up during a rough patch. But sometimes, and I know some people may not agree with me, an optimistic outlook is not for the best. When the going gets tough, I think it’s important to be realistic, and I often find a friend or family member’s optimism irritating or just plain irrational. In my opinion, a little pessimism can come in handy — sometimes you have to plan for the worst! But where do you stand on this glass half-full or half-empty issue? Do you think optimism is harmful or helpful?
