I cant understand goal setting

Many people use goal setting to become successful. Well I don’t really have a grudge on them or anything its just that I don’t believe that goal setting will make you successful. For me life is short and that is why you must enjoy every bit of it. you must gain all the experience that you can because we only have one life. Goal setting makes people concentrate and focus their life in their future thus making them live life for tomorrow not for today. Most of the people focusing on their future does not know how to have fun. That reminds of my friend who was so focused with his career that he forgets to relax and have fun making him being left out all the time. He felt bad about it so he messed up his life telling his family that he had enough of everything. That his not having fun with his life and that its useless to live for tomorrow.
