Your boss, who would take as much as you are willing to give.
Your needy friend, who hasn’t stopped to consider the effect they have on your well-being.
Your kids, who are too young to realize you might have needs of your own.
Always others who will take your time if you let them; always distractions that seem worthwhile in the moment.
Always something or someone who will prioritize your life for you if you don’t do it first.
It’s not about being selfish.
It’s about recognizing that you can’t do everything, and guarding some attention for the things that matter most.
