Everything, including travel, must begin with a single step. Otherwise, you go nowhere, you'll be just dragged by things and circumstances you currently find yourself in, to places you don't necessarily want.
I'm not sure, but I think travel is something very natural for us, and something that we need, you know, like drinking water, eating, etc.
What this quote above means for me, is that in going into places you haven't been before, you broaden your perspectives, you gain knowledge and understanding (having new eyes), you learn about those places and at the same time, you learn to love your own (your country). I say the latter because that is what I realized, having been to South Korea as an example. It made me appreciate more of what we have here in the Philippines :)
Lastly, be open to adventure. If you are like me who likes to plan everything ahead of time, don't be mad if things don't go the way you planned it. Don't be too tough on yourself and allow some margin for error. Enjoy every bit of it. As for me, I enjoy everything, starting from the planning phase, all the way through to completion. It's the journey and not so much the 'destination'.
