All of us,' he said, 'have hopes of being poet, artist, discoverer, philospoher, scientist; of possessing the attributes of all these simultaneously. Few are permitted to achieve any of them in daily life. But in travel we attain them all. Then we have our day of glory, when all our dreams come true, when we can be anything we like, as long as we like, and, when we are tired of it, pull up stakes and move on. Travel -- the solitude of the mountains, the emptiness of the desert, the delicacy of the minaret; eternal change, limitless contrast, unending variety.' (Eric Lang)
The thing about traveling alone, is that you run into your insecurities and fears times ten the normal! You run into all the good things and all the bad things about yourself on a daily basis, and are allowed the opportunity to truly become your own friend. Traveling alone is a learning process; some people travel for leisure, I travel to run into myself!
