Nowadays, people are so busy with their lives, that they can't stop to think about their life purpose.
I think that all of us have at least one purpose in our lives. Maybe a small thing, that posteriorly will become a huge thing. Maybe our purpose is ”just” simply live a life like it's the last day. Maybe all of this that we are living is just a game where we will don't lose or win. Maybe we are here to see how beautiful is Nature or complex can be our brain and body. Maybe we are here to be a support to each other. Do you ever stop to think about the true definition of ”life”? I think that there's no correct definition for that little big word. Every one of us has to think about our lives. Not to think about the other’s life, because it will distract us about our way.

Just live life as if it were the last day and be grateful for everything that happens.
