In general, an essay should have an introduction (one paragraph), a body (number of paragraphs depends on the topic and how many words it shoud have, but it should have at least 3 paragraphs) and a conclusion (one paragraph).
As for the content, you can write about the topic in general, but it would be easier if you chose a specific example. It can be a true story, or you can make one up, since it is far more important how you write it, than whether it is true or not. One of the easiest examples would be a parent or grandparent.
You could start by saying that a great number of people pass through a persons life and that we look at other peoples behaviour, replicate the things we like and dismiss the ones we don't. Everyone looks up to someone, especially when we are young and impressionable and at different points of our lives we admire different people. If you are writing about a family member, you should say that there was one person that you especially admired and always looked up to. You could write about your early childhood and how impressed you were by that person, how wise/interesting/brave you thought they were. You should mention the things that that peson taught you, how he/she affected the decisions you made. Later, you could write about how you grew up, changed, and how you see things differently, but that person is still your hero and that you wouldn't be the person that you are today without him/her.
No, the sentence given:
_________________________
"<span>i came home late; therefore, i didnt see aunt matildia" — is NOT punctuated correctly.
____________________________________________
The word: "didnt" should be replaced with: "didn't" (note the added "apostrophe")—or rewritten as two word: "did not".
Furthermore, there should be a "period" at the end of the sentence.
___________________________
As far as other grammar errors are concerned, the second instance of the use of the personal pronoun, "I"—is incorrectly written in the lower case: "i"—and should be replaced with the capital letter, "I". Furthermore, "</span>aunt matildia" should be rewritten with a capital letter "A" replacing the word: "aunt" [the word: "aunt" should be changed to "Aunt"], and the name: "matildia" should be rewritten with a capital "M" replacing the name: "matildia" [the name "matildia" should be replaced with "Matildia"]. Also, if "Aunt Matildia" is, in fact, really spelled that way, than the spelling of the name should be retained. On the other hand, if the aunt's name is actually spelled: "Mathilda"—or some variant, then the proper spelling should be used—and the first letter should be capitalized.

--Edit--- your question should read as follows: "Is this sentence punctuated correctly?"
