Here to help with all your written communication!
Words are a powerful tool. Perhaps the most powerful tool in humanity's toolbox. They allow us the ability to distill complex concepts into simple forms that may be communicated universally between diverse groups and individuals. Words allow us the formation of language, and the ability to grow beyond the simple pictographs, runes and hieroglyphs of our distant ancestors. Without words, we wouldn't be where we are today.
Finding the right words can be a trial. The right words grant one the ability to inspire, to influence, and to innovate. The wrong words can destroy lives, livelihoods, and reputations.
A misspelled word can lead to a misinterpretation of intent, to a misrepresentation of ideas, or even to further mistakes. They make one appear unprofessional, incompetent, or just plain silly. It is the duty of a proofreader to find those errors in punctuation, grammar, and spelling. Before they become irrevocably and indelibly printed for all the world to see.
Nothing is more embarrassing than a typo. Especially if that typo leads to a global misunderstanding.
Thankfully most errors don't fall into that category. They are mere footnotes in the life of a professional writer. Everyone has them. Even the most prominent professionals will have typographical errors in their history. It isn't wrong to seek help from others to correct those errors before they become a piece of one's personal history.
