Well,in answering this question, there is a clear difference between purpose and goal.
Purpose first is the reason you are born and the reason you exist.
Goal is something which we strive to achieve.
Purpose is something that influences goal. Purpose is the reason for achieving the goal.
Everybody was born with a purpose and we exist because of purpose, most people mistake goal for purpose just as people mistake ambition for vision.
Firstly,in life we have to discover our God given purpose and then do all it takes to fulfill it,it is the process of fulfilling your purpose you set goals on daily basis or stipulated time to hit your target.
