Have you ever put part of your life on hold? Maybe for a month or two, maybe for a year, maybe for an era? If so, write about that today: why you did it, how you felt about that choice at the time, how you feel about it now, and so on.
If you have ever put your life on hold, reflect on the topic and think about where you have seen a particularly powerful example of someone putting their life on hold (maybe for you!) and how you feel about their choice now.
