A knight in armour sits on a horse that is rearing up. His tunic is patterned with salamanders, a flame-like plume streams from his helmet, and behind him rise the same pyramid-shaped hills as in the Page. The horse looks ready to bolt. The Knight of Wands is someone who acts the moment they decide — or that way of moving.
It could be you or someone around you. The colleague who is first to say 'let's just try it'. The friend who makes up their mind and hands in their notice the following week. You, booking the moving date before properly seeing the flat. This is a time when the body moves before the plan, and right now speed is an advantage. If an opening would slip past while others hesitate, this is the person who grabs it.
Reversed, it splits two ways. One is recklessness: jumping in without looking, cooling off just as fast, and doing it again next month. The other is the reverse — all talk and no departure. You have announced you are going several times and still have not left. Both have heat and no direction.
The check is whether you can say where you are headed in one sentence before you set off. If you can, the speed becomes strength. If you cannot, it is just noise.
A lot of people read the Knight only as 'a lover is about to appear'. As a court card it can mean that, but the point is the manner of the approach: hot, fast, and possibly not staying long.
With the Chariot, the drive is strong enough to carry through to a result. With the Knight of Pentacles, a fast person and a slow one are on the same team, and matching pace becomes the real work.
