But to convince Yale students to start marrying earlier, it is necessary to know their objections to early marriage. One is the fear that a romantic commitment will limit their post-graduation plans by forcing them to factor another person’s needs into their career choices. This is immaturity, and they should be told to get over it. Accommodating another person’s desires is an important part of being an adult, and if people don’t learn that skill before they marry, they are going to get an unpleasant crash course in it when they have kids. It is foolish to think that, with careful planning, one can construct a marriage—or, for that matter, a happy life—that does not involve sacrifices, and the sooner this is learned, the better.
