Making a change in your career is no easy task. I have worked with several clients who are attempting to do just that and it ain't easy. I mean it is kind of a big deal. Certainly not a decision to take lightly.
If you are on the precipice and considering taking a leap, might I suggest a book to help you along the way. The book is called Life's a BITCH and then You Change Careers and was written by Andrea Kay, a well-known career consultant and executive coach. It's basically a "how to" guide that walks through 9 steps of changing careers. You can get through the book at your own pace and it's easy to reference if you need to.
Changing careers is not easy, but as I said before in a recent post, progress isn't typically made by doing what's easy. This book won't make it easy, but it should aid in taking some of the guess work and trepidation out of the equation. I hope it helps and good luck!
