Introspection and navel-gazing do not take you anywhere in life.
You may feel superior to your fellow men because you spend hours wondering and expounding on the mysteries of life, but ultimately, it leads you down a path of self-destruction.
In the still, long hours of the night, your mind works busily while you body cries for sleep. You question who you are, you think of all the things in life that need to be experienced and accomplished, and you worry anxiously over things that will never happen.
Yes, introspection takes you nowhere in life.
You instead remain stuck, glued down in one spot, in a spot where you will never be entirely happy, where you will spend all your energy and time thinking things should be a certain way.
