It depends on what you mean by 'travel'. I think spending anything less than a month in a place just makes it more like a visit to a theme park than anything enlightening.
That's why I spent 2 years driving from Alaska to Argentina, learning Spanish as I went, and am now spending two years driving right around Africa, learning French and Swahili as I make my way around!
I have learned more in the last 12 months of my life in West Africa than I did in the 34 years that came before...
I learned the western media is only a fraction of the truth, and often for various degrees of "truth". There are hundreds of millions of people being impacted by how I choose to live in the western world. Those people want the same things I want. Those people are extremely kind, friendly and generous - about a million times more than people in the western world (yes, West Africans make Canadians look unfriendly)
Self-sufficiency is a great thing. People friendly gets you a long way, even with guys with guns. Being polite is the best way to get ahead. The entire world is severely corrupt, many developed countries just have a different word for it, like lobbying. Many international corporations are evil and severely fuing up the planet and millions of people who live in it. A massive number of foreigners in West Africa are making it worse, not better.
I'll write a book about my trip, which will not be random, and I will flesh out many more points in detail.
Back when he traveled, this was before airlines and even the Titanic. "Traveling" required spending months to get places far away so you certainly didn't spend just a week in a single place and then return.
My wife & I do still get a lot out of our backpacking travels, which nominally last two weeks but feel like a month or more.
