Are goals necessary to achieve success?

In my opinion, goals are not necessary to achieve success because being successful can be other than what you think. If you set goals and try hard, the chance of achieving what you want will increase, but it doesn\'t mean that you are successful. Rather, having positive mindsets is necessary to achieve success. I was a goal-driven person when I was in high school. I tried not to think of things other than studying in order to enter an university I dreamed. When I passed all the requirements and the interview to enter the university, I realized that I was not happy. Even though I achieved what I wanted, I felt empty and became afraid of other things that I have given up in order to study. Since then, I don\'t like to push myself too hard to a single goal. Rather, I came to believe that being successful is to be satisfied with what is given.
