I tell beginning readers to read a lot and write a lot. If you want to write a book, find a subject that's really worth the time and effort you'll put in.
If you're against globalisation, it doesn't achieve much by sort of bombing the head offices of Shell or Nestle. You unsettle people much more by blowing up an Oxfam shop because people can't understand the motive.
We almost always have choices, and the better the choice, the more we will be in control of our lives.
