Ale told us about an essay he wrote. He described three types of challenges that we face, and used different types of walls we need to get through as an analogy. Some walls you have to power through. Hit them and hit them until you break them down. For example, perfecting a musical piece on an instrument often takes practice and more practice. No short-cuts. Other walls, are too hard to demolish. You must find a path around them. An example would be a rock climbing challenge. Sometimes, the answer is a different move or path, not more "brute force". Finally, there are some walls we should walk away from - as they can't be demolished nor have a path around them. So, when you face a serious challenge, determine what kind of "wall" it is be and what the correct approach to overcome it is.
