Undergraduate / 'harsh workout every morning' - Common App to Binghamton early action. [5]

The beginning is great, but then I lose your point. "Through pains, unfavorable conditions, and unfortunate weather, I run because I made up my mind three years ago to succeed" would be a great thesis for an essay where you could go on to talk about why/how you made this decision and the effect it's had on your life. You have 500+ words for the common app essay, so I think you could develop your ideas a lot more. Great imagery, however.

Undergraduate / 'Receiving help from others' - University of Michigan essay, the qualities attract me [7]

My biggest advice to you is to tell a story! Your essay will be so much more engaging if you talk about a time that you felt guilty for receiving help and how that inspired you to want to help others.

How long is the essay supposed to be? It seems kind of short, and I think you could develop your ideas a lot more.
Watch out for grammar mistakes:
From the time I can remember, I have.. I think you mean "for as long as I can remember"
whether if they are a stranger or who I know. Whether they are a stranger or someone I know.
Myself, not my self
Help not helps
You have many more mistakes.. but don't get discouraged. I would suggest revising your essay and then once you have a draft you want to submit, sit down with someone to make sure you have no mistakes.

Overall, I like your idea! Work on telling a story and developing it more.
