The speech of Steve JobsSteve Job's Speech

In English, important words are captialized.
We rarely use "of" when refering to something that someone owns.

Yesterday, I listened the to speech that Jobs gave at a university graduation ceremony.

He said that he never graduated from a college.

While technically correct, Americans use drop the adjective when talking about college.

What he learned at that time was those really interested him.

I have also read some biographyies of other famous figures, some of whom have dropped out ofrom college too.

It’s seems that if you want to become successful, you shouldn’t go to university.

In my opinion, the reason why they are successful is thatbecause they doid something right, not because they lost those things they lost.

In those speeches orand biographies, the leadauthor stresseds what they sacrificed, and weakened what they did to gain.

-- if we are talking about a book's content, we are talk in the present tense.
-- I didn't understand the second chunk.

So reading is far from being success, do moreful. We must practice more and try.

The usefulness of those speeches may only be getting your out ofrom trough periods,; they can’t guide you to success.
