Getting an off-campus work permit will legally let you work for 20 hours per week while studies are in session, and up to 40 hours during vacations (some restrictions apply). My first job during university was as a Program Host for Jet Set Sports during 2010 Vancouver Winter Olympics (highly paid fun with free admission to all official Olympic venues). I had to get an off-campus work permit in order to be legally allowed to work, which took me about a month to acquire.
I recently read “The Richest Man In Babylon” by George S. Clanson, which was originally published in 1926. This book contains a lot of interesting thoughts, and is a good read. The main point I got is that in order for money to constantly grow is to spend 7/10th of your income is for living expenses, 2/10 for paying out debts, and the remaining 1/10 is to be put aside to save, until you have enough to invest in something; and when investing for a profit, take advice from those who are experts in their field. With the profits be careful, and re-invest in order for the money to keep growing. Do not spend pointlessly what can be maintained for a rich financial turnover.
