The meaning of life is a question of "who am I" and "what am i here for?" With the Answer "To Be", as whom you were in past is not the person you are at present, and the person you are at present will not be the person you are in future, as every new sight, sound, thought, interaction, etc. changes you either in a split second or progressively over time, leading to a little more wisdom... While serving God is a calling many hear, few consider, less undertake, with acts one should attempt, being a difference.
