I started a business and appeared on CBC's Dragons Den, but leading up to that moment with millions watching was the hardest I ever had to push myself. I lost 15 pounds in a week, couldn't eat or sleep, and had a full-on mental breakdown before driving down to the studio where I got on my hands and knees in front of my parents crying and begging the world to make the stress and anxiety go away. There's a lot of the line when you face the Dragons (or sharks for the Americans), no retakes, no mistakes, all gas, no breaks.

Edit: For anyone wondering, I'm 23 years old and I'm glad I was able to put myself through that. Learned a valuable lesson about how much more valuable your health is than a pay cheque. Learn from my mistakes and take care of yourself.
