Being a single person searching for love teaches you that not everything is under your control. You can’t control whether the person you’ve fallen for will call. You can’t force yourself to have feelings for the nice guy your best friend fixed you up with. You have no way to know whether attending this or that event — a co-worker’s art opening, a neighbor’s housewarming — will lead to the chance encounter that will forever alter your life. You simply learn to do your best, and leave it at that. Relationships are work, but so is being single.
