Everything in life answers to purpose. Trees, Birds, Fishes, all works of nature even everything you have in your apartment is subject or meant to fulfill one purpose or the other. No wonder the popular say; " When the use of a thing is not known, abuse is inevitable". Knowing one's reason for being on the planet earth makes life meaningful. There is never a dull day. One is full of passion and can't wait for the next day to dawn. Unfortunately many on the planet earth are yet to know their purposes on earth. It is better to know what your life is about before even attempting Studying in the higher Institution. You graduate knowing you won't say "yes sir or ma" (that's if you will ever work for someone else) for long. Life is meaningless when reason for living is unknown.
