That was the clear thought that shot through my head as I fell down the steep rocky north face of Zugspitze, Germany’s highest mountain. My knee and shoulder smashed against the rocks, and I screamed in agony. Despite the pain, I couldn’t help but smirk internally as I scolded myself for making such a stupid decision that could have cost me my life. Spoiler alert: I survived. But I learned some valuable lessons the hard way.
