If you don’t show up today, will you be missed?
Will someone notice, write you a heartfelt email or a message asking if everything’s OK and when you’re coming back?
Will it be more challenging for someone to do their best work?
Will it be a bit harder for your coworkers or community if you’re not around?
If your answers are affirmative, you’re doing an excellent job. And if not, try to figure out how to provide more value.
