Hi,
On the college admission, I would do several things:
1) I would really focus on the attributes(like value,experience,your academic & personal assets,your desire to help other & move foward in life...) and make that my "bread & butter" of all the essays. As for Ivy.Lea. schools yes mention that it would be an honor to attend that particular college but dont get overwhemed or spend too much time on that cuz you want to believe,think and write as ANY college would be lucky to have you.
2) I would then have that essay as my template which is saved and then simply tweek it for each essay to explain why: you would be a great fit for that school and your reasons for wanting to attend there.
3) In your writing & if you have to interview keep your focus on: being your self & demonstating confidence & humility.
4) Have realistic expectations when writing your essay. It may take a while and force you to think a lot. Mine took me a long time because I believe this it is YOUR chance to show them all you "bring to table".
5) Talk to successful people,read up on books & online on successful ways to write an essay such as this.
As for your other question, I am unsure what you meant? If you explain a little more I can probally help you.
Best wishes with your college essay and truly enjoy your college experiece!!! It is like your senior year in high shool a very special time if you let it be.I attended college for many years & earned advanced degrees but do to circumstances I didnt attend full time until age 29(although I enjoyed & absorbed every second of it & maybe even had a greater appreciation due to my age.) so I missed out on the experince of being 18 & going off to college.
Most important as mentioned above "Just be yourself,so you can relax & enjoy!!!!!!!!!!!!!!
