Travel interrupts familiar routines and brings novelty, which can help us discover more about ourselves.
Travel takes you out of your daily routines. The familiar sequence of places, tasks, and habits gives way to new surroundings and new choices.
That novelty is a big part of why people enjoy travelling. Away from the life we have arranged for ourselves, we get to notice what we are drawn to, what we miss, and how we respond when things are unfamiliar.
Perhaps travel helps us discover more about ourselves because, for a little while, we get to see ourselves outside the usual routine.
