You and all five of your roommates have a not-so-healthy love of Mountain Dew. First, maybe switch to diet? Second, turn all those empties into a healthy chunk of change by bringing (rinsed!) cans and bottles to your local recycling center. If you alone drink two cans per day everyday, at an average 5 cents per can, you could have more than $35 at the end of the year, enough for a few weeks of laundry—or a steak dinner.
A traditional way of earning money in your student life is selling your old notes. This is a one-time money making way yet this can be extended putting in some efforts. Students are always searching for someone who would write notes, make presentation, assignments, practical files and projects for them. This can be your mean to make money and somewhat gaining knowledge as well. Writing notes for students can be paid in accordance to one page basis. This was something a fellow mate in my college use to do and he made some decent money for the same. ClearSlide, Prezi, and Slideshark are some other platforms for making impressive presentations that will help you get paid. There is one flaw in the Indian education system, that is, students can always copy the projects of former batches which presents us with a new way to make money. Utilising the contacts, one can also come up with small shops like the ones which take orders for making presentations, working models and charts. This will also polish, the student’s skills and earn him/her a good pocket money.
BigSpot.com is an easy way to earn some money on the spot by reviewing products. If you have a car, let people rent it or sign up as an Uber Driver in your free time. Vancouver is pretty busy and one of Canada's largest cities, so no doubt there will be quite a bit of Uber users. Task Rabbit is another way: depending on your location, it sends you on a lot of tasks (for example, Walmart sends you to take photos of their products, etc.) Fiverr gives you five bucks for doing certain tasks: like, writing a love letter, or attempting to eat wasabi. Field Agent pays you to check prices.
Busy professionals outsource their laundry more often than you would think. If you live in a dorm or apartment building, you could offer to start a laundry service for all your friends and neighbors. Instead of them having to make their own trip to the laundromat, you could combine their trip with yours, and charge them a small fee for it. Considering you do laundry each week, this could be a great recurring revenue stream.
