Trekking to Mount Everest Base Camp and back was, by far, the hardest thing I've ever done, but I'm also not the same after having done it. It was the most amazing, challenging, wonderful, painful, hard, and life-changing thing. While there are obviously many challenges along the way, there are even more beautiful moments. You meet amazing people, you push yourself further than you ever thought you could go, you see what you're really capable of, and you get to see one of the coolest places in the entire world. Embrace it all — the pain, the emotional roller coaster, the dirt, the discomfort, the breathtaking scenery. You absolutely won't regret it.
