Why do we need goal setting

Most people use goal setting in their lives some do it on purpose and some are unaware but no matter how or why,  goal setting is very important and effective in everyone’s life. Your success depends on your goal setting. I had a friend when I was still a child he was 2 years older than me and whenever we got together he would tell me all sorts of things. How he wanted to be a doctor someday, that he wanted to travel and do all sorts of things. At a young age he had set his goals and worked up to it he used his every actions as a stepping stone to achieve his ultimate goal of becoming a doctor. Now after 15 years my friend is a successful doctor who travels the world and help people in different countries. He has achieve his goals and ambitions and that is because he focused on achieving them.
