I've never had a problem with public speaking, but I know it's a widely held view that talking in front of people is something most folks would rather not do. The only thing worse for them I imagine would be singing, also something I don't have trouble doing.
Be that as it may, here is an interesting piece about how if you have any hope of succeeding in business public speaking is going to be part of it. The author is Martin Zwilling, CEO and founder of Startup Professionals, Inc.
I found this little tidbit the most interesting part: "(Being) able to speak in public is one of the five key business skills
that can make or break your company, whether you are a new startup or an
entrepreneur who's been around for many years. The other four are: new
product development, writing, time management, and sales/marketing. Many
would argue that Steve Jobs impact at Apple came more from his public
speaking ability than the other four skills put together."
So if you're still looking for a new year's resolution, perhaps you might make it your mission to become more comfortable speaking to people.
