It's totally true.
Or, more precisely, there's that long, hard, agonizing struggle to learn stuff, where you become (as a writer) like the proverbial centipede after somebody's asked it to walk, and you need to practice, to be conscious of every step, to find your balance again and learn how to learn.
And then you do that.
And then later, you need to learn to do most of it without thinking, again.
It's simple, but it isn't easy...? Heck, Hannah, I wouldn't say it's simple either. It's incredibly complex, and you just have to keep doing it until you forget how complex it is and just start doing it.
Like driving a stickshift on ice....
