Being positive is important because often a person’s attitude to their work can come across in their writing and presentation. 

Example ::

An admin plays an important role in ensuring that diaries are properly managed and that all outgoing correspondence is well written and all incoming correspondence is read and delivered to the relevant managers quickly. Administrators sometimes provide the first impression a customer has of a business, so a positive and professional outlook is needed at all times.

The error is in third part. The adjective hard has two different adverbs, and they express opposite meanings. The adverb hard is used to modify a verb and means that the action is being done very intensely. The adverb hardly is used to modify a verb and means that the action is not being done very intensely. So there the correct usage will be ‘working hard’.
