I really dig Thoreau....
“I have climbed several higher mountains without guide or path, and have found, as might be expected, that it takes only more time and patience commonly than to travel the smoothest highway”
-Henry David Thoreau
“Public opinion is a weak tyrant compared with our own private opinion. What a man thinks of himself, that is which determines, or rather indicates, his fate.”
-Henry David Thoreau
"It is never too late to give up your prejudices."
-Henry David Thoreau
To me that last quote can really relate to travel and learning about new cultures.
You know my favorite strangers to smile at? Servers and people in customer service like the cashier at the gas station or the clerk at the bank. These people deal with a ton of people everyday, most who are rude and unpleasant. Sometimes all these people need is a sweet smile and a friendly hello. I know because sometimes it makes my day when someone is
actually nice and understanding.
