"I know it's cliché to say, but I don't see it as work because I love doing it," said Kyle Bergman (pictured).

• Kyle Bergman is the senior buyer for men's grooming and lifestyle at Birchbox, a beauty subscription service.

• He also runs The Great Fantastic on the side - selling sweatpant overalls, or "swoveralls."

• In the rest of his spare time, Bergman plays lacrosse for the Israeli national team, teaches a class at OrangeTheory Fitness, and attends a part-time MBA program at NYU.

Kyle Bergman's always been a busy person.

He attributes that to his years as a student-athlete in college. He also credits his productive parents, who he said seemed to handle their packed schedules with ease.

"I was kind of already conditioned to juggle a lot," he told Business Insider. "It's really what gives me energy now. It's really what gets me up in the morning and excited."

Today, he's juggling quite a bit. Not only does he have a full-time job at beauty subscription service Birchbox, he also runs The Great Fantastic, his side business that sells sweatpant overalls. He also plays for the Israeli national lacrosse team and is in a part-time MBA program at NYU.

So how does he stay productive while managing so many activities?

"I'm not the most organized person, but I live and die by my calendar, whether it's scheduling to pay rent or doing a strategy presentation for my job at Birchbox," he said. "Everything is on my calendar."

Here's a look inside his jam-packed daily schedule:
