Balance between learning and applying: "The paradox for knowledge workers is this: the more time you spend in gaining knowledge, the less time you have to apply it. The reverse is also true. We must strike a proper balance between learning and doing. Most people have their nose to the grindstone. Very few spend enough time, energy and money in a quest to gain and process knowledge."
Comment: Learning is doing. I don't think that sitting in a classroom, reading books, attending conferences, etc. is learning. I think those are examples of knowledge acquisition. Learning has to be evidenced in actions/behaviour to qualify as "learning". Learning is actuated knowledge.
