I did this and after submitting clips and going in for an interview I was hired. In the meantime I continued to write for several other publications and had an article accepted by a national magazine. I guess you might say that I sort of fell into the journalistic end of writing, and because of my business background I am able to help other business people to write effective letters. Speeches are a favorite of mine. My experience as a professional speaker allows me to give individual coaching when necessary.
Studies show that public speaking is one of the worst fears people face.
This doesn't have to be the case. The secret is to have a speech that is well prepared and a plan to see that you yourself are well prepared. Then giving a speech can be a pleasure rather than a chore. Yes I did. Determination is the key.
