For this topic of discussion I am going to take more of a real life slant on the topic. If I were Premier for a day I wouldn't make any changes what so ever. This is not because I think that no changes should be made, or because I think the country is perfect the way it is. I would not make any changes for the simple reason that I don't have the knowledge or the experience to make changes that would benefit the country as a whole.
I would instead take that day as Premier to do things that I would normally not be able to do. Things such as meeting MP's and other important political figures. I have always had an interest in politics and I think that being Premier for a day would greatly impact my decision to go into politics or not. It would have such a great impact on that because it would provide a first hand experience into the world of politics. Instead of trying to base my opinion on politics on what I read, I would be able to see first hand what politics are really like. I would spend my day not making radical changes, but learning if I want to try to make those decisions in the future.
