If you can write well - you can sell well. Many of your bigger competitors employ professional writers to pen their websites, brochures, and even their email correspondence. If you seriously want to compete, you'll either need to make the same investment or learn the craft of writing for yourself. Your words reflect you - and your business. If what you write appears unprofessional, your potential clients will assume that your services and products are too.
Writing is definitely therapeutic.
It's a real tonic - healthier than a stiff drink, and much cheaper than an appointment with a shrink. If something is bothering you, or if you're in a muddle - write it down. Whatever the problem, it certainly appears to be much clearer once it's down on paper. Pour your emotions onto each page and rid your system of any bad vibes. More often than not, you'll wonder what was wrong in the first place.
