Maybe I should pit this on the theories area but I'm not especially confident, so here it goes... Is it possible that the Night Watcher takes something from one person and gives it to another? For example: a guy named George wants to learn to farm buts is a great warrior. The Night Watcher takes his ability so skillfully swing a sword, and gives him the ability to farm. Then Bill comes along and wants to be a great warrior, but has no skill. The Night Watcher offers George's curse, not able to swing a sword, and gives it to Bill (meaning Bill now has Georges ability to swing a sword). Then takes a skill/part of Bills and gives it to someone else. Its a continual pattern and could explain why Cultivation herself had to give Dalinar his specific Curse and Boon as the Night Watcher simply didn't have the ability... Could this be how it works or am I just off?
