I hate when people say "if you could learn any language" or "if you could learn any instrument", because there's no if. You can. What is it that makes these things valuable (rather, admirable or envious) to us? The time and effort put into them. Almost everything that comes easy is not worth learning. Learning that comes easy isn't really learning at all. Becoming knowledgeable is an act of creation. Knowing doesn't come from nowhere. Everything I know has made me who I am, by virtue of having learn it. There is no endpoint to learning, either. It's a process that must be renewed through will, passion, discipline, or what have you
