Chesca Potter's Greenwood deck calls the 9 of swords 'Dedication' and the visual depiction of this card is quite beautiful (see attachment). From this point of view, all the shades of dedication may form the basis of the lessons learnt, i.e. ranging from lessons about the negative polarity (obsession/over-focusing/loss of perspective/inability to see the big picture/context) through to the learnings about positive polarity of this concept (dedication and the ability to remain focused and produce great works, such as the archer does when s/he shoots the arrow directly into the bull's eye). As I see it, drawing this card as your life lesson indicates that you have incarnated with an ability focus intensely - in this life you're learning about how to handle that ability wisely, including what, why, when, how, where and who to focus upon.
