Greatest people were normal?

Is it true that most of the Greatest people in this World were normal person like one of us ?

I guess that your statement is fairly true, if you really choose to take a good close look at people that achieve greatness- they are most likely somewhat screwed up in one way or another.
if you choose to define movie, and music celebrities as 'great'- you will really notice a great deal of dysfunction in their pasts.
so it could be said that - greatness is born of hardships and dysfunction.
and those who manage to somehow never face hardships in their lives- lead rather boring, inconsequential lives.

Yes Jesus was a person (human being) like us and he was very important and still is!

Of course.

In many ways, they were normal. But they also had extreme personalities to some degree. I'm slowly reading a biography of Ghandi and he was a great man but he was obsessive and prepared to sacrifice a lot for his goals. His goals were good so that was great, but he wasn't 'normal' in that way.

Alexander the Great surely wasn't 'normal'. How could anyone normal do the things he did before the age at which he died (32)? But he did some normal things, like fall in love, too.

I tend to find biographies of great people quite annoying, because they have been single-minded and careless of other people as they achieved their goals. I despise them a little, however much I admire them.

I'm always intrigued that I don't feel the same way about Jesus. (I'm a Christian.) How was anyone so good yet so un-annoying?
