[Serious] What are exact keys to do great in life?

You need talent, dedication, and luck.

I've known a lot of different "successful" people - - DC politicians and lawmakers, pro athletes and Olympiads, world-renowned scientists and Hollywood actors. At the end of the day, though, they're all just as human as anyone else. I think "greatness" is generally restricted to one particular area of endeavor.

The only people I've ever met who I would describe as "great men" were two NASA astronauts I met on different occasions. They had a presence. Military background, Ivy League education, peak physical, and a never-quit attitude.

There was also one Marine Corps captain I served with when I was in the Army who I also respected immensely.
