Why you should travel young

1 Dr. Eisenhautz  was a German professor at my college. I didn't study German, but I was a foreign language student so we knew each other. This explains why he felt the need to strike up a conversation with me at six o'clock one morning.

2 I was about to start working out, and he had just finished. We were both getting dressed in the locker room. It was, to say the least, a little awkward – two grown men shooting the breeze while taking off their clothes.

3 "You come here often?" he asked. I could have laughed.

4 "Um, yeah, I guess," I said.

5 "That's great," he said. "Just great."

6 Then, he just blurted it out. The most profound thing I had heard in my life.

7 "The habits you form here will be with you for the rest of your life."

8 The words rang in my ears for the rest of the day. Years later, they still haunt me. It's true – the habits you form early in life will, most likely, be with you for the rest of your existence.

9 I have seen this fact proven repeatedly. My friends who drank a lot in college drink in larger quantities today. Those with no ambition then are still working the same dead-end jobs.

10 "We are what we repeatedly do," Aristotle once said. There is an important lesson here: Life is a result of intentional habits.

11 Youth is a time of total empowerment. You get to do what you want. As you mature and gain new responsibilities, you have to be very intentional about making sure you don't lose sight of what's important. The best way to do that is to make investments in your life so that you can have an effect on who you are in your later years.

12 I did this by traveling. Not for the sake of being a tourist, but to discover the beauty of life – to remember that I am not complete.

13 There is nothing like riding a bicycle across the Golden Gate Bridge or seeing the Colosseum at sunset. I wish I could paint a picture for you of how incredible the Guatemalan mountains are or what a rush it is to appear on Italian TV. Even the amazing photographs I have of Niagara Falls and the American Midwest countryside do not do these experiences justice. I can't tell you how beautiful southern Spain is from the vantage point of a train; you have to experience it yourself. The only way you can relate is by seeing them.

14 While you're young, you should travel. You should take the time to see the world and taste the fullness of life. Spend an afternoon sitting in front of the Michelangelo. Walk the streets of Paris. Climb Kilimanjaro. Hike the Appalachian Trail. See the Great Wall of China. Swim through the Great Barrier Reef. These are the moments that define the rest of your life; they're the experiences that stick with you forever.

15 Traveling will change you like little else can. It will put you in places that will force you to care for issues that are bigger than you. You will begin to understand that the world is both very large and very small. You will have a new-found respect for pain and suffering, having seen that a large number of people struggle to simply get a meal each day. Traveling allows you to feel more connected to your fellow human beings in a deep and lasting way. In other words, it makes you more human.

16 While you're still young, get cultured. Get to know the world and the magnificent people that fill it. The world is a stunning place, full of outstanding works of art. See it.

17 You won't always be young, and life won't always be just about you. So travel while you can, young person. Experience the world for all it's worth. Become a person of culture, adventure, and compassion.

18 Do not waste this time. You will never have it again. You have a crucial opportunity to invest in the next season of your life now. Whatever you sow, you will eventually reap. The habits you form in this season will stick with you for the rest of your life. So choose those habits wisely.
