You should totally write one. Maybe the fact that it seems so easy is your brain's way of telling you that you'd be good at it. I really couldn't say if you'd be any good at it or not so soon after meeting you, and telling you what I do, and listening to you disparage my life's work and all.
Then again, if you notice you're often saying "I could do that" when confronted with all kinds of things that are easy to do but difficult to do well (non-representational art, haiku...kid's books), then it might be time to put up and get your hands dirty. Yes, anyone can smear paint around, anyone can count syllables, anyone can write a very short story about bears learning to share or whatever.
You may even think, having crafted a bear story with a beginning, middle, and end, that it's fit for publication. Maybe you'll ask me who to talk to about that. I could give you the names of a number of editors, each of whom literally rejects thousands of stories per year. Because she doesn't think they're good enough. Or she doesn't think they're sellable. Or she doesn't think they have anything going for them besides a beginning, middle, and an end.
I wonder if you like the NPR comedy news quiz show Wait, Wait, Don't Tell Me. I usually catch at least a little of it each week, but I missed the episode a couple Saturdays ago when children's book agent Brenda Bowen got to be one of the call-in contestants. Here's a link to the transcript if you're interested–it's what got me thinking about all this.
Anyway, one of the panelists kicked things off by essentially mentioning that she suspects it would be easy, writing kid's books; and Paula Poundstone, whom I must say I like, nevertheless trotted out a variation on an old chestnut that I assume every kid's book writer has heard at least as often as I have. It always goes something like this: these books are a snap to write, which I will now exemplify by mentioning a board book I saw once that contained only pictures of shapes or farm animals or the alphabet. Because surely the fairest way to evaluate any vocation is by its most rudimentary example. SpaghettiOs. An elementary school dance recital. US Weekly.
Or maybe it's a question of length? Certainly I've heard that often enough–"It's only thirty pages and there's, like, ten words on each page. How hard can it be?"
It's a high school composition approach to writing–if a 500-word essay is hard, then a 1,000-word essay is harder. A novel must be harder to write than a short story. A really long novel must be harder to write than a novel.
May I suggest you try something?–write a brand new, memorable quote. Something we'll still be repeating a hundred years from now, like people are always doing with Twain. It should be easy, shouldn't it? It only needs to be, like, ten words.
Or is it hard to think of something worth saying? And hard to think of the perfect way to say it because, with so few words, each one has to really count? My stars but that's interesting.
And then you have the audacity to say I'm "lucky" to be doing what I do.
No, you're right about that, actually.
On deck for tomorrow: another post about how hard it is to be me. Maybe something about the headaches of having a beautiful, intelligent wife.
