According to Steve Pavlina, in his blog post entitled How Selfish Are You? – yes and no.

He defines two concepts:

STO – Service to Others
STS – Service to Self

Says Pavlina:

STS and STO must remain in balance. It isn’t a matter of choosing one path over the other. You need both.

….For example, suppose you’re in a situation where your job is almost entirely STS. You do it for the money or for other perks or for a feeling of security, but your work doesn’t serve the greater good in any meaningful way. Suppose your company manufactures junk food, the kinds of products that are only going to harm people’s health in the long run. But your company (and you) get paid to do it.

Then in your off time, you do volunteer work, spend lots of time with your family, and so on. In your personal life you try to be a lot more STO.

STS and STO are in conflict. They’re not in balance.

How does one find balance?

Pavlina suggests:

Instead of having [STO and STS] work against each other, set them both after the same goal. Allow your greed to fuel your service and your service to fuel your greed. Accept and integrate both the selfish and the selfless parts of you. Learn to use both the dark and the light sides of your nature.
