If you put in a lot you get out much more than you put in. The successful have magnanimity of spirit, an ability to give, that's why. They may appear careful, even mean sometimes. But watch their whole life style. It will be magnanimous.
Unstinting generosity creates fortunes.
It is vital, too, that we have, and stick to, our opinions and beliefs. Not in a silly, dogmatic, closed-minded way but in a way that prevents us from changing our views with each new bit of information. We all know of vacillating managers who change direction more often than an outback swarm of locusts. They may consume everything on which they alight but they will die in the end. Not enough singleness of purpose.
