This card came up as the solution for the problem represented by the 8 of wands. Aren't they both about speed and focus
8/Wands involves speed and focus but not intelligence or thinking. You're passionate about something, and you race after it, like running for the finish line. Knight/Swords (as solution) tells you to cool down. Stop being so passionate and hot, and use your head.
And I think the picture of the Knight on the Horse says it all quite well: Consider a horse race. The horse has focus and passion. It wants to beat out the other horses by going as fast as it can right away--that its nature after all, and it does that instinctively and with no thought.
Which is why, in a horse race, you've got a jockey on the horse's back. The jockey's job is to think. He holds the horse back so it doesn't waste all its energy right out the gate; so it has reserves for when they are near the finish line. He directs the horse in and around other horses, close to the fence or away from it, whichever will serve them best. He keeps his mind and focus clear and cool, so that when he sees an opening, he can give the horse that all important kick and they can finally go for it.
8/Wands is the horse. Knight/Swords is a jockey on a horse. Be the later, not the former. The former may get you where you're going, but you'll end up there with no more energy and maybe damaged. The later will get you there with energy to spare and in great shape.
