But, no matter how fun it is, how productive it may feel, it is important to remember that thought does not make reality. No matter how hard you think, and how sure you are that you've got the whole universe figured out and lying prone at your feet, back in reality where people have to work to put bread in their mouths, all you've really accomplished is a whole lot of mental masturbation. Thought, while it is an important component in grounding ourselves in our human realities, when taken too far, can have the opposite effect, transforming what might be useful members of society into abstract philosophers who have their heads so far up their asses they are mistaking their stomachs for an ultimate Truth.
In the end, your brain is not a penis. There are more flattering ways to use it than mentally jerking off and having your own psychic cum dribbling down your face.
