Motivation vs. Result

Here's one stuff that has been troubling me - the fact that people constantly keep confusing between motivation and result. And why this is so important is that this causes people to mix-up selflessness and selfishness. Even the conscientious people tend to manipulate because of this.

Let me explain...

"I help and I feel good as a result" is very very different from
"I help in order to feel good"

Thanks and Warm Regards,
