Good ideas, like traveling to a country alone, really help people grow in many different areas of their lives. This twenty-six-year-old went to Costa Rica by herself. And even though she barely spoke Spanish and was a petite female, she decided to go on an all-day hike deep in the jungle.
She was flown on a small plane to the middle of the jungle, where she then had to begin a 26-hour walk to the next town. Once the plane took off, it was just her, the guide, and a machete. She quickly realized the mistake she made, but there was no going back after that (via The Brainy Penny).
