[elcapitan]

I liked the comparison with walking the solid board over high ground. This is something I actually use quite literally to fight my (light) vertigo. The other trick (maybe more important in that situation) is to avoid switching back and forth between looking at what's close and what's far away, because that's the part that irritates my sense of balance and then creates the vertigo effect. Not mixing up close and far away makes actually even more sense than the 'first step' metaphor in what the article is trying to say.
