Well, you're on somebody else's schedule for the next many years. Get out of the late night feeding world, and presently you're coordinating schedules with day-care providers and then schools (not always to be distinguished) that you cannot afford to upset. (I vividly remember one Friday afternoon at the end of the government fiscal year; some chosen software was taking a divide-by-zero error on DOS 4.0, and the COTR wanted to know whether she should pull the invoice and buy from a competitor. Meanwhile I had a babysitter who needed a check before she left the country for a couple of weeks. Fortunately, a quick repartition to bring C: back under 32 MB fixed the problem. I was home by 5 pm.)

It does not make everything else seem uninteresting--children can open up new areas of interest for you. But your priorities change drastically.
