Let us grab a shovel, go searching and start digging to find out what life purpose is all about. If you dig deep enough, you are bound to find answers...or something. People are always searching - searching for keys, searching for answers, searching to find themselves, searching for reasons to be happy, searching for reasons to be unhappy, searching for excuses of why they procrastinate, or searching to find themselves.
Search, search, search and more search. I am not sure where exactly people are expecting to find their lost belongings and answers, but on and on they search.
