take more time out for myself

i think every woman with children that has a full time job has this problem.we do not take enough time out for ourselves.it has been my experience that even the small things get put off.it could be as simple as taking a bubble bath or reading a book in peace and quiet but even the little things get pushed to the sidelines.and i always seem to tell myself that i will do it later and i never get the time too. even when i do have the time i am generally to tired.someday i will master motherhood and find a way to do all of things and still take care of myself.i just hope i do this before i am 50.
