Prime Minister Julia Gillard says the best piece of advice she's ever been given was from a teacher in primary school.
"My favourite teacher Mr Crow said 'always be happy but never be satisfied, so don't go around scowling. We live a very good life here in this wonderful country, but never be satisfied and always aim for more than what has happened today'," she said.
