And why not you ? When I wrote out all of the things I've done, I realised I'm a good role model, I realised the parent who brings up 3 kids on their own, the nurse, the policeman, the soldier, the doctor and so many more, these are all role models.
What have you aspired to be and where's the book about it ?
You can virtually do anything as a job / career nowadays ... teach kids to follow THEIR Dreams and Goals !!
