Don’t forget to bring a towel
I have been reading the hitch-hikers guide to the galaxy series and have kinda become addicted to it. I don’t read novels too often but they really are amazing books.
My favourite character is Ford who spends his whole life hitch-hiking while writing articles for the guide (And going through crazy experiences as if they were nothing). But I especially love the idea that the most important item anyone can own is their towel. In their universe none of the crazy advanced gadgets or spaceships or technology is important. It is all disposable, but not their towel.
It draws a parallel to the real world. Not specifically towels, they are pretty useless as they are. But we have all this technology; Televisions, Cars, Computers etc.. and it is all disposable crap.
What is the most important item that exists? no clue. But the simple, cheap and common items do tend to be the most useful things around.
