THE LAW OF SERVICE by brian tracy

You are ultimately paid for results. The good news is that you can increase your value, and ultimately the amount you earn, by increasing the quality and quantity of your results. And in the long run, there is no other way.
The most successful men and women in our society are those
who are able to “lose themselves” in serving the people who depend
upon them, their customers, their employers and others, for what
they do.
The 100 absolutely unbreakable law of business success by Brian Tracy
