I swear, I'm not just writing this article because I write for a living. 

Buying a journal and actually using it is arguably the cheapest therapy.

I've been abroad for almost two months, now, and without journaling every day I'd have no idea what I did. Everything moves so fast, not just traveling, and journaling helps us take a moment to slow down and remember the ups, the downs, the emotions and moments that made those 24 hours more than just the usual sunrise to sunset. 

Journaling helps to remember, reminisce, and appreciate life. Things we never expected to discover about ourselves often come out in the written word -- whether it's a rant, a declaration, or a simple account of the day that makes you reevaluate every other that has occurred before. The power of the written word, although on the way to extinction thanks to online publishing and blogging, is not lost yet. Some thoughts are still better in the written form where you can see them just as they are.      
Epiphanies or moments of clarity can often come when writing down what happened, or what may be bothering you. We often never really know what's getting under our skin until we write it down and sort it out on paper. Mathematicians follow their lives through calculations and probabilities, but if that's not the life for you, then write. Writing is often the only escape we have, reminding and removing the burdens that weigh on our shoulders with every word scribbled down.      

So write, I say. Even if the only person who will ever read it is you -- especially if the only person that will ever read it is you. Take advantage of the stacks of old journals given as a cop-out gift from the extended family for all those years and write about it. There's nothing more therapeutic in the world.
