Get it done within scheduled time

I have finally reprioritized and recommitted to getting done what I planned on getting done by now.
I have only one week. What can I do to make sure I get it done? I know that there’s Get It Done program and workbook within SCS but I have no time to go through all that in detail. I must get started on my project.

Please give me specific steps and models I can practice while getting done the project. THAT will be the most helpful right now.

Thank you.
