Many people who are getting married or about to have kids worry whether they will be good parents.
There are many things that are said about good parenting. I believe that good parenting is subjective. I believe that what is important is fulfilment (sense of well being) regarding the choices you make for your family as a parent. One parent will be fulfilled to say he passed up on making more money so he could witness his child being born while another will be fulfilled to say he missed the birth so he could make money for the child. None is more important that the other. It depends on your values and that you did what you believed was best for your children.
