You know one thing that has always bugged me? Well, not always. It began bugging me when my kids were young and society started telling all kids, "You can be anything you want to be." Because---no, you can't.
It didn't bother me when I was a child myself, and my dad told me that. Yes, back in the day when girls were told they could be either teachers, nurses, or secretaries, provided they remained unmarried, my father actually told me I could be anything I wanted. At the time, I felt euphoric. But in the long run, bless Dad's well-meaning heart, it just wasn't helpful, and I say that as the holder of a business degree who has just about zero head for business.
It didn't matter that I entered college having never met the academic subject I couldn't master; in fact, that made it worse. I chose, and stuck to, a math major (my other degree), but otherwise I barreled around my school's academic offerings like the proverbial bull in a china shop. "Okay, should I maybe pair that with a biology minor? I like biology. Maybe I could teach... Hey, wait! Computer science. They say computers might be big someday... Naw, English! How obvious! But I'll have to read a string of boring classics... Hmm, okay, I'm at the end of my sophomore year, halfway done. Options are getting limited. Business. Huh, that should make me employable, and I've got time to add it as a major... What's that? They're starting an accounting major? That might be cool. But if I end up doing taxes the rest of my life I'll scream... My friend said, 'You can always work at a bank,' but I dunno... Maybe I could be a stockbroker!"
Nobody can be anything, because nobody is suited for anything, even if they like or want it for a time. More than being told we can be anything we want to be, we need to learn who we're meant to be and aim toward that. We need to figure out how to discern the good, the better, and the best. And to face that saying yes to the best may mean saying no to the good and the better, maybe just for now, or maybe forever. What we need to equip kids and ourselves with is a way to narrow down all the delights that beckon and decide which are for us and which are to be left to others. In short, we need to find our own particular calling and destiny.
If that's not writing (or science, or ministry, or stockbrokering), we either won't make it, or will feel unfulfilled when we do. If it is writing (or medicine, or fine arts, or mothering), we have no viable choice but to set aside the excuses and distractions, even the good ones, and do it.
