“The purpose of life is to find its purpose.”
“Finding the purpose of life is a life long journey.”
I am sure you have heard of above statements and probably are having your own challenges in this area.
I think here we got mixed up between discovery and invention.
If something already exists, one can just go ahead and find it. Re inventing would be pointless and usually much harder.
On the same token, if something does not exist, however hard we try, we are not going to be able to find it. If we need it, we have no choice but to go ahead and create it.
