When you step into a new work situation of any kind, it is imperative to establish a reputation for results as soon as possible. Novice professionals sometimes make the mistake of misconstruing the reason why they are hired or contracted. Companies, clients, and customers only pay for services for one of two reasons. It is either to make more money or save more money (which is essentially making more money). While having a great attitude and personality are assets to help get your foot in the door, only delivering results will keep you in the building and enable you to advance further within it. Find a way to make yourself indispensable and very difficult to replace.
