How can i stop feeling guilty when i take time out for myself?

Remember: You can try to remember what airline attendants say during their talks on basic flight safety. In the event of a drop in cabin pressure, put your own oxygen mask on first -- and only then help others with theirs. Unless you're nourished, rested, and cared for, you will not be able to care for others who need you to be at your best. Self-sacrifice and human flesh have limits.
