Prime the Pump

Each Friday afternoon, I write a summary of my work week that includes my achievements, the impediments I encountered, and my goals for the next week1.
This last step proves to be quite valuable the following Monday morning.
I start my week with my weekly review. One of the first things I do is review the goals I set the previous Friday. This way, I can shake off the Monday morning rust and immediately aim for something. It eases my way into a work headspace and my work week.
This process reminds me of the advice to end your writing sessions mid-sentence so you can carry that momentum forward when you next sit down to write.
