Would like some sources to back up the following three points:

* Financially succesful people tend to rise early and work long hours.

* Financially succesful people tend to be have large networks of
friends/mentors/associates/etc.

* Financially succesful people tend to spend carefully.

Maybe you could define "financially successful?"  Career?  Assets?  Happine$$?

Sometimes it's hard to tell exactly who is really successful, versus
who is heavily in debt, but "rich" with shiny toys.

The three you mentioned are generally correct, except some activities
require working til midnight or later, so early to rise would be
harmful to most of these people.
 Spend carefully can become a distructive obsession, so moderation is appropriate.
 Working smart is more important than working long. A successful
person often appears to be loafing, but they are analyzing and
gathering opinions from mentors about the details of activities they
may be doing soon.  Neil
