My brain often moves far more quickly than my mouth. Some people that know me may be surprised, with how often that I talk, that I often can’t keep up with what I’m thinking. Because of that, sometimes ideas come out very awkwardly through speech. This is why I prefer so much to write. Even when instant messaging, I can be far more articulate and able to express things a lot more succinctly than with speech. This is due to the fact that my words can flow more quickly than they could ever come out of my mouth. But trust me, finding this voice in writing took me quite a while. All of the many instant messenger sessions and notebook scribblings I’ve had over the years have a lot to do with why I write so well now.
When I was in high school, students were often forced to write their essays in the dreaded five-paragraph format. Of course, being the passive-aggressive rebel I’ve long been, I often neglected to write that way. Because of this, I was graded poorly on many assignments. I was just going to let my words flow without any regard for the restrictions they were forcing on us. These restrictions seemed ridiculous to me. I had been developing my writing abilities for several years up until that point. Still, I have to admit I was a fairly poor writer in junior high, because I still hadn't yet found my voice. By the time I got to around my sophomore year in high school, however, it was clear that I had developed a specific style. No one could make me deviate from it. I'm glad I stayed the course, because while my voice is far more refined now, it's the same voice I started writing with back then! So, my rebellious nature when it came to developing my own writing style allowed me to bring you the work you get to enjoy today.
Of course, the lesson here is that all it takes to develop a voice is practice. Don’t let anyone try to force any arbitrary rules on you, besides conventions of grammar and spelling - which are good rules, of course. It's really as simple as just writing as much as you can and about as many topics as you can. Build your vocabulary and simply exercise your writing abilities at least once a day. You’re going to struggle at times. A lot of what you write may not look too great to you later on, but you need the exercise. You'll find that after enough practice, eventually you'll actually start to find yourself writing very naturally. Even without having some innate talent for it in the beginning, anyone can write given the proper practice and devotion to the craft. Once you develop that voice in your writing, you can write about anything, anytime, anywhere!
Outside of public speaking, writing is the best way to do it. Of course, the greatest public speeches were written first, too. Be a rebel. Make your voice heard. Everyone has a voice. Don’t ever let anyone else tell you otherwise.
