Iā€™m the master of the side-hustle.

While I was in graduate school I, in the same semester, held down a three-days-a-week unpaid internship, marked papers for a post-existentialist philosophy course, tutored English to high school students and poured beer at sporting events on the weekends.

The only time I didnā€™t have multiple streams of income was when I worked a 9-5 communications job. I foolishly thought I had a high-enough salary that I didnā€™t ā€œneedā€ to work that many jobs anymore. I started organizing my nail polish alphabetically and taking two-a-day yoga sessions because I was so bored.

But besides the boredom, relying on only one source of income eventually became just too nerve-wracking. Like many milennials, Iā€™ve never enjoyed a permanent full-time job -- theyā€™ve always been part-time, temporary or contract. So I started writing freelance articles, both for my own pleasure, and also to gain a second cashflow to tide me over any bumpy career gaps.

Now that I write full-time, I still spend several nights a week cracking open cans of tall boys and serving tequila shots to Torontoā€™s nightcrawlers.

The extra money, while not strictly necessary to make ends meet, helps me pad my savings account and eliminates any guilt I may have with buying

Other millennials with better-than-average money management skills generally feel the same compulsion to seek out more than one job.

ā€œIā€™m trying to think of a time when I wasnā€™t working at least two jobs,ā€ says Bridget Casey, a 29-year old in Alberta. ā€œBut theyā€™re essential to any financial success that Iā€™ve enjoyed.ā€

Besides working full-time at a start-up and running a website, sheā€™s also worked as a chemistry tutor, waited tables and babysat, among other positions.

Initially, it may seem like you donā€™t have time for an extra gig, but the best ones are flexible -- you can schedule them on your own time, and there are many you can take on from home. Having a packed schedule also forces you to be more productive.

ā€œI think people donā€™t know how much they can do until they start doing it,ā€ Casey says. ā€œAnd once itā€™s part of your routine, you stay in the energy to do it.ā€

She gets up early to work an hour on her website before her 8-5 finance job, and then spends another hour or two on it in the evening.

ā€œItā€™s nice that Iā€™ve always had side-income from things that Iā€™ve enjoyed doing,ā€ Casey says. ā€œSo thatā€™s made it easier to balance because theyā€™re essentially profitable hobbies.ā€

Itā€™s true that a second job can be so much more than just slogging away at a part-time position at the mall or restaurant. An ideal side-hustle can help you develop your skill-set in a way that relates to your primary job, and can also serve as a a creative outlet.

Caseyā€™s friend, for example, set up an Etsy store where she would sell custom-painted shoes.

ā€œShe would paint Toms, the shoes, with whatever people wanted, like Blue Jays logos or characters from video games,ā€ Casey says. ā€œThey would just send in a request, sheā€™d go buy the Toms for $50, sheā€™d spend a day drawing whatever character design on them, and just sell them for $100. And it was the easiest business ever.ā€

It helps that finding extra streams of income isnā€™t particularly hard, especially not in these days of online classifieds, and theyā€™re much easier to find than full-time positions.

ā€œIf thereā€™s something that youā€™re good at, thatā€™s what you should capitalize,ā€ Casey says. ā€œAnd thereā€™s always a way to do that.ā€

Check out these easy side-hustles with maximum flexibility:

  • Take part in the sharing economy: become an driver if you own a car, rent out your couch on or offer your carpentry skills on .
     
  • If you have design skills consider creating business cards for .
     
  • If you live in Toronto or Vancouver, check out . This is great for students since thereā€™s so much waiting around on sets, youā€™ll get a chance to study.
     
  • Put that English degree to good use and romance novels.
     
  • If you have typing and computer skills, join a to get receptionist work. I did this on Bay Street and spent the entire day on Facebook.

  • Use your youth and social media skills to your advantage and run the Twitter feeds and Facebook pages for businesses.
     
  • Give music lessons; the more obscure the instrument, the better the pay.
     
  • Sell garage sale finds on eBay, Craigslist or Kijijii.
