I think theres a lot to be said about just enjoying your work. It can be very contrived when people say their work is for the good of mankind.

The person they're working with, is going to be the person they'll know more. So if that person leaves, they're going to go - well, should have I left too? What did they get and how does that compare to my deal.

The bigger you get, the harder this gets because the more aggressive the people working for you are.

To succeed at selling a losing product, you must develop seriously superior sales techniques. In addition, you have to be massively competitive and incredibly hungry to survive in that environment.

Planning is valuable, tho the plan is usually useless.

Hire sales people who are really smart problem solvers, but lack courage, hunger and competitiveness, and your company will go out of business.

There are no silver bullets.
