I think the joy of discovery is one of the most profound human experiences possible. There is nothing even remotely similar to discovering the thing you never knew you were incomplete without. People rarely know what they want. Why do you think so many lead unfulfilling lives? Why else would depression be at an all time high in an age where one can literally live anywhere or do anything they desire with little more than a whim and and some initiative required?
No, people don't know what they want only what they have had.
I like this post a lot. Well said.
