I read this post on LinkedIn the other day about why it's important for leaders to be able to write:
Whether you’re scribbling a quick note to your team or crafting a feature-length article, you reveal a part of yourself in what you write. The nuances of your writing — word choice, sentence structure, references, and tone — are like interlocking puzzle pieces; they come together in your reader’s mind to create an image of you, the writer.
What struck me was how all the various details of your writing come together to help the reader form an opinion of you -- an opinion that may be inaccurate.
For example, I'm a guy that converses with most in a tongue and cheek manner. However, when I have to be buttoned-up, I can do so. However, when it comes to write, I like to keep things brief and strip away the nonsense. Get in and get out. That's my writing style.
To some of my readers, that may create an impression of me that comes off as I'm trite, rude or don't care. It's the opposite. I'm just not trying to waste anyone's time.
