1. If your uni happens to have a free BBQ every once in a while then bring an empty bag. You'll need to waste a bit of time and line up for the sausage more than once. At least, until you've filled your empty bag. That way, you'll be able to cut down on food costs for that week. (Every Tuesday @ UoW!
)
2. Borrow friend's stationary. Do not buy any yourself.
3. Share a textbook with a friend. Last session, I knew of three people that shared the same text. Amazing organisational abilities is required to perform such a feat.
4. Recycle paper. Write your notes on the 'other' side of some random pieces of A4 paper.
Think of some other later..gtg watch movie.
