I am, first and foremost, what you might call an armchair traveler.
I often travel using nothing but my imagination. In a way, we all create inner journeys, often surpassing those we undertake physically. Traveling often combines visiting exotic places, and experiencing adventures, qualities that characterize all trips.
Fictional traveling aside, undertaking a physical journey is for most people the more common way to travel. We visit foreign shores on family vacations, go to bustling cities, the natural world's beauty, and stand in awe in front of ancient sites.
No matter how you travel, the experiences of undertaking a journey will always fill your memory bank with more adventures, new smells, new visions and will forever alter the way you look at the world and beyond. That is in itself, perhaps, the most important benefit of any travel.
