5. There’s a good chance you’ve met the person you’ll marry.
By thirty, you’ve probably been in a relationship with the man that will be your husband or there’s an ex that has taken some time to get his stuff together so he can come correct. Even better, that marriage will more than likely last longer than most. Knot Yet, a project that studies the correlation between marriage, children and income among other things, published evidence that not only do women who wait longer to marry earn more, but have marriages that typically last longer. Worst case scenario: You’ve been in enough sucky relationships or awkward dates to know what you do NOT want in a man, or that you might have some work to do on yourself.
