There's a business reason why this advertising CEO draws amazingly detailed sketches and posts them to Instagram every day

Adam Padilla is the cofounder and president of BrandFire, a boutique Manhattan-based advertising agency that has worked with clients including Run DMC, the Manzo family (made famous from the reality series "The Real Housewives of New Jersey,") Tom Brady, and coconut water brand Zico.

But aside from his day job, Padilla has also set himself the task of drawing a sketch every single day, which he posts to his Instagram account.

What started as out a one-year personal challenge too soothe a creative itch has turned into a long-running project. He went from having just a couple of hundred Instagram followers to more than 30,000 and now he encourages every member of his team to follow his lead and challenge themselves creatively outside of work every day too.

We spoke to Padilla about how the drawing-a-day idea came about and whether it has a positive effect on the business.
