Travel releases spontaneity.

"Travel releases spontaneity. You become a godlike creature full of choice, free to visit the stately pleasure domes, make love in the morning, sketch a bell tower, read a history of Byzantium, stare for one hour at te face of Leonardo da Vinci's Madonna dei fusi. You open, as in childhood, and - for a time - receive this world. There's a visceral aspect, too - the huntress who is free. Free to go, free to return home bringing memories to lay on the hearth.

...

In our carpe diem state of mind, we decide to take a big risk and live by our wits. Travel will be tied to a bigger word, freedom. ... Everything I pick up seems to lure me away. Everything I do in my daily life begins to feel like striking matches. The need to travel is a mysterious force. A desire to go runs through me equally with an intense desire to stay at home. An equal and opposite thermodynamic principle. ... The balance just slightly tips in the direction of the airport."
