The 7 lessons I learned as professional traveller were:
Know before dusk where your next bed is going to be.
You will only ever need what you can fit in a laptop bag.
Dirt roads exist to make journeys. Airports exist to make business trips.
When feeling lost, continue straight for just five more minutes.
A tourist becomes an explorer while breaking bread with the locals.
Places worth stopping at have strange foods, interesting people and a view.
And finally, often the only escape you require awaits in a good book, at home.
