Wealthy people do have some common habits and traits about them i agree.

And if you don’t do anything with what you know, nothing happens. Knowledge well used brings wealth. Wisdom well used, brings happiness.

This is absolutely right, i have seen the most successful people love reading, i think it's the knowledge that they get that makes them rich, if you think about it, few people love reading and the few that do it really make a difference.
Being able to recognize opportunities instead of wining about everything comes from having accumulated knowledge.
