Describe your short and long-term goals and how you plan to accomplish them. (1000)

Life has no meaning without goals. I set up my life goals regularly and plan to accomplish them step-by-step. My current short-term goal is to graduate from high school with high grades and to learn as much as I can so I will be prepared for college. It will not be that difficult to reach if I am responsible to my academic courses and put in the required effort before a test to show what I learned. Along with that, I am also working towards my scholarships so I can afford my education. By accomplishing these short term goals, I will finish the first step that is going to reach my dream, which is to become a doctor. There are people who are suffering from disease in developing countries. Another goal I want to achieve with degree is to help these people get better health conditions. In order to accomplish that, I will engage more volunteer opportunities at local hospitals to gain experience about how to take care of people and what to expect in the future.

Be more specific in your response. I think this paragraph is a little too general and unoriginal. But I don't see problem with grammar.
