AG -

good list so far.
I would say successful people all have extremely detailed goals that call for a plan of action and stick to that plan of action on a daily basis no matter what. whether that be cold calling everyday from 7-9am then off to lead generation from 9-10, then team meetings from 10-12.... blah blah blah. they don't vary, they know what they need to due in order to meet those goals and they don't stray from the path.
Extremely focused, because what you focus on expands.
Positive attitude.
surrounding themselves with other like-minded individuals.
I think very successful people have "the big picture in mind" they have really big dreams/goals so they are constantly striving towards something without hesitation. I don't think they compare themselves to other people, I think they hold a standard to what they believe they have as their own potential.
I'm a firm believer that clarity is power, and once you know what you want, and know what needs to be done to get there, success is simple, not easy.
