Famous quotes containing the word exception:
“For a parent, its hard to recognize the significance of your work when youre immersed in the mundane details. Few of us, as we run the bath water or spread the peanut butter on the bread, proclaim proudly, Im making my contribution to the future of the planet. But with the exception of global hunger, few jobs in the world of paychecks and promotions compare in significance to the job of parent.”
—Joyce Maynard (20th century)
“There are two great rules in life, the one general and the other particular. The first is that every one can in the end get what he wants if he only tries. This is the general rule. The particular rule is that every individual is more or less of an exception to the general rule.”
—Samuel Butler (18351902)
“Lets face it. With the singular exception of breast-feeding, there is nothing about infant care that a mother is innately better qualified to do than a father. Yet we continue to unconsciously perpetuate the myth that men just dont have what it takes to be true partners in the process.”
—Michael K. Meyerhoff (20th century)
