You're making the mistake of thinking that the place you're headed is your destination. When you look back (I hope) you recall fondly your younger days adventures where you had 2 bucks and an open road. The best adventures happen when we don't expect them because we're on the way to the 'important' thing.

We very rarely correctly identify in advance what the important thing is.

I disagree that I'm making that mistake - I'm saying that 5 days in some foreign city can be filled with adventure just like 5 days on a bus through unknown areas can be.

Why not 5 days traveling and 5 days more in Rio? Or 50?

Sure, I was just assuming a scenario like "I need to be in rio in 6 days for a job" or whatever
