Seriously, Marcia? Consider doing the Seth Godin class all on your own...a dry run, if you will. It will help reposition you towards offering Krypton classes. If you won't lead, who will. Find a few other committed individuals and make it happen. Why? Because it resonated with you. You need this. And if you need this, someone else needs this, too. If it were easy, everyone would be doing it. I can promise you that on the other end, you will be amazed what you will discover about yourself.
You CAN do this...if it is important enough to you. Get rid of doubts and only put out there your beliefs.
