There are times when your work will not logically conclude at the end of your work day. This can be tough if it’s a particularly vexing problem. If you must leave something undone, take steps to be fully present for yourself and those around you during your non-working time. Unburden your mind by leaving notes to yourself about what your immediate next steps are when you pick up where you left off. Make a plan in your calendar to finish the work. Then, leave.
