What are some good strategies for coping with tasks that have high "wait times" when using the Pomodoro techinque?
Right now I'm about 15 minutes into a pomodoro, but I'm waiting for a program to finish running. I know that the program will take at least another 25 minutes to run. Until it's done, I can't do anything else for this task, although I could make progress on other tasks.
Should I switch to the other task, knowing that I will have to switch back in a few minutes? Should I "slack off" while the task completes?
Should I sit there and stare at the screen waiting for the task to complete?
Is there a better idea?
