This document discusses the importance of sharpening your "axe", which represents preparing yourself mentally, physically, emotionally, and with skills/tools before embarking on your own path in life. It states that from birth until around age 16, your identity and path are determined by others, but at 16 you must start working on yourself and the "jungle" of the world. To sharpen your axe, you need skills, tools, time, effort and attention, and should understand your identity, gather relevant skills/tools, and continually refine yourself.
