Set Manageable Milestones
It's helpful to create milestones to give yourself an ongoing sense of accomplishment. Trying to complete a huge project may feel like climbing a gigantic mountain. It can be intimidating. To reduce your stress, picture each phase of the project as a small hill to get over.
For example, my publisher and editor needed this entire book completed by a certain date. Writing a book is a big job. But I broke it down to one chapter at a time, which made it more manageable for me. I “budgeted” my time every day to meet the deadlines we'd set. And with each chapter I completed, I felt more confident that the job would be done according to my client's needs and within the timeframe on which we had all agreed.
