I think it's important to set reachable goals and to break large projects into bite-sized chunks. An example? We once had a huge exhibition area to get in order. There was a warren of small rooms and an enormous hall. My team thought it was a daunting task until I broke it down into little sections.

My attitude was "think of the space in sections. The completion of each one giving you a little victory." We actually had fun making a team game out of it. This can be applied to any task to help you move forward one step at a time.
