Attitude is sum up of beliefs, feelings, and behavioral tendencies towards socially significant objects, groups, events or circumstances. Your attitude determines how you will act in coming moments independent of the circumstances that is present at the moment. If you have a go-getter, positive attitude at work, then you've decided to stand firm before circumstances present themselves that you're going to come out on top. This shapes you how to encounter different situations. The locus of control is within you, not your environment.
