please feel free to add new points or any idioms that will help me.

I like the way you organized this according to the ideas they suggested. You will make a good impression if you write 7 paragraphs: an intro, a conclusion, and 5 body paragraphs that go with each of these 5 topics.

But what is your BIG IDEA? The reader will finish reading and remember only one big idea. What will that be?

I think all these 5 ideas should support one big idea that has something to do with your plan for the future. The reader will respect you a little or a lot depending on how detailed your plan is (even if it might change) and how many short term and long term goals you mention.

That's the secret! :-)
