When you have a great and difficult task, something perhaps almost impossible, if you only work a little at a time, every day a little, suddenly the work will finish itself.
When you have a task or job that seems overwhelming, try tackling it in small portions and you will notice the task that seemed so big and daunting at first is not so big after-all. Stay focused. Set realistic goals with deadlines. Ask for help if needed and remember to stay positive.
