I recently heard an interesting piece of advice pertaining to how to articulate yourself better, and therefore how to ultimately think in a more clear and precise manner. The advice came in two parts. First, read frequently. To broaden not just your vocabulary and mastery of your language, but to discover fresh ways of thinking, different world views, to garner the ability to derive a truly nuanced viewpoint about anything you may come to ponder upon. Wise. The second part was to write. To write daily for at least 15 minutes. It's one thing to think about something intently for a prolonged period of time, but to take the jargon of incomprehensible, unorganised, and flimsy thoughts that form the basis of an overarching idea, and to articulate it neatly, with precision and impact, well that's something else entirely. The ability to externalise your thoughts, and view them objectively from an outside perspective, is to allow yourself to be truly analytical of what it is you think, and to wrestle with the notion that what you think may be an incredibly weak manifestation of an idea. To write it down and to try and pick it apart serves to not only better your ability to lay down something comprehensible and well formulated, but tot ensure that it is true to your own standards, and likely other people's standards, of what makes a thought worth thinking about.
So that's what I'm going to do, the next time I find myself running casually down a line of enquiry within my own head, I'll stop. Write it down, and make sure what I'm think can be both articulated properly, and is worth articulating.
