You should read a ton.
I mean you should be FANATICAL about reading.
And this should never end.
You should be a student for life.
However, may I caution you, if you wish to be a responsible leader, you should at some point, start to develop your own path.
And your path should consist of your convictions.
At some point, you ought to be able to clearly articulate, in your own words, what life is all about.
Do you quote, or are you quotable?
