This woman traveled to all 7 continents before her 30th birthday

Michelle Miller, 34, has worked in sales in Chicago, as a bartender in Florida, and is now a farmer in rural Iowa, working to bridge the gap between farmers and consumers through her blog, Farm Babe.

But there's one more title that she proudly holds: world traveler.

From backpacking through Europe to meeting penguins in Antarctica, Michelle Miller made it to all seven continents before she turned 30.

How did she do it?

"It's about setting a long-term goal, picking the date, committing to the date, and then staying on track to reach your goal," she said. "Always set a goal."
