In my 20s I believed there was such thing as enlightenment. Now in my 40s, I don't believe in that anymore. Some people decide to focus on problems and that inevitably leads to insights. It doesn't matter if the problem is programming a GPU, baking bread, making music, or understanding your inner world. Obviously the longer you advance on a road the more insights you will have. We get wiser as we get older simply because we've lived longer. In Spanish we have a saying "El diablo sabe más por viejo que por diablo" which can be translated to something like "the devil knows more because he is old than because he is the devil".
