They recognize that there is a cost for not doing, just as there is a cost for doing. As an example, they know that by not making one additional call per day they can save some time and perhaps get out of the office at a normal hour.

Be available when they're available and be aware of the consequences of your behavior. They invest in themselves so that they continue to get better.
Entrepreneurs recognize that they're either growing or they're struggling.
There is no opportunity or value in standing still. Because they are entrepreneurs, they're not waiting for someone else to invest in them or to teach them. They are interested in growing themselves. Recommending the latest book or tape you've read speaks volumes to them. Entrepreneurs set and commit themselves to deadlines to increase their decision-making capability.
