Great advice, Aleksandar!
Yes, so you can tart by writing a topic sentence about each goal. Then, add an example and some elaboration to each topic sentence, so that each becomes a paragraph about a goal.
Then, go back and write an intro paragraph of 4-5 sentences to explain the theme and philosophy for your education at this point in life. End that intro with a thesis statement that names the 3 goals.
Write a conclusion paragraph that discusses the 3 goals thoughtfully and goes on to discuss your future a little. Really enjoy writing this, because it is a meaningful thing to do!!
