It's only part of the equation...
I love Toastmasters! Its a fantastic organization and you cant beat the value for the education that you get by participating. The mentorship and the feedback on your projects will take you to the next level in your craft. And if you choose to attend advanced and specialty clubs in the toastmasters organization, the sky is the limit. However if you want to be a professional speaker, you cant rely on just toastmasters. You see, Toastmasters will teach you the "craft" of speaking. But they will not teach you the "business" of speaking. You will need training and systems for marketing, prospecting, logistics, tech, and a host of other things that you never imagined that you needed to consider. For that half of the formula, I would recommend the NSA. No, not the cyber spies for the government; I talking about the National Speakers Association. They provide classes, workshops and resources for the business of speaking industry. I highly recommend that you find your local chapter and as soon as it is in your budget, join and dive in to everything that they have to offer.
