The other part of learning these types of skills is the importance of experience. Experience tells us what to expect in a given situation - and more importantly (if we're paying attention to our mistakes), how to respond. Experience (now) tells me that if my young dog splits off a sheep during a training session, I can let him retrieve the sheep as long as he's not abusing her. The first time something like this happened, I reacted poorly.
Finally, gaining skill and experience is often easiest when we're working with someone with more of both! Someone who has fried lots of chicken is a more effective teacher than a website or a cookbook. The physical nature of these skills requires tactile learning to be effective - a video about how to make homemade fried chicken can't describe how a piece of chicken drops off the fork when it's done.
