If someone asks “what’s the meaning of life?”, they will find cliché answers, well reasoned ones answers, etc. But nothing explains it better than what this guy did.
“I discovered that no one had ever gone to every country in the world completely without flying [in one unbroken trip].”
Now, if doing what you want, and makes you happy (without harming others) isn’t what life it all about, I don’t know what is.
