I attended A.C. Grayling's launch of his latest book. He eloquently communicated difficult ideas in an entertaining way. I left with a new found motivation to write and communicate my own "interpretation of the times we live in." If you want your encore career to be in writing, I do recommend you see as many author book launches as you can, then read their work. A good writers habit incorporates a mix of researching, writing, reading and editing.
