How to motivate yourself and stay focused

 When you have concerns, allow yoursefl to think about it for 30 min or so instead of just supressing it. Then go back to work.

Have an accountability partner like your boss or colleagues; to set a realistic deadline to get things done.

Set small and realistic goal for each day. 2 hours reading, 1 h writing, eat lunch, exercise, come back to writing, and reading again.

Set up an environment that's similar to my office.  Put up a goal on the wall.

Check in with your officemate that's productive and efficient. Get inspired.

It's an uncertain time, lots of changes to get adjusted to.
