"You cannot do everything well at the same time. You cannot be a 100 percent wife, a 100 percent mother, a 100 percent church worker, a 100 percent career person, and a 100 percent public-service person at the same time. How can all of these roles be coordinated? Says Sarah Davidson: 'The only answer I come up with is that you can have it sequentially. At one stage you may emphasize career, and at another marriage and nurturing young children, and at any point you will be aware of what is missing. If you are lucky, you will be able to fit everything in.'
"Doing things sequentially—filling roles one at a time at different times— ... gives a woman the opportunity to do each thing well in its time and to fill a variety of roles in her life. ... She may fit more than one career into the various seasons of life. She need not try to sing all of the verses of her song at the same time.
"The Book of Ecclesiastes says: 'To every thing there is a season, and a time to every purpose under the heaven.'” (Eccl. 3:1.)
