A great book - big ideas, many want ideas bigger than just ads. Something that makes them go "wow!". Ask yourself these simple questions about every piece in your book. Can people understand it? Is it different? Does it get a reaction (like wow! cor! ha ha! amazing! Jesus!)?
Nice people - no one hires arseholes, arrogant students, prima donnas, smart arses or idiots.
The right attitude - be prepared to work hard, be grateful, listen, learn, look for opportunities, be positive, accept criticism.
