They see the same thing, yet process it in completely different

ways.
It all boils down to our beliefs and attitudes towards others.
One can be an optimist, and the other can be a pessimist. One can be ambitious or simply condescending.
We can see ourselves as part of this world. As contributing to it's progression.
Or we can view our lives as an attempt to simply rise up above others for the sake of it.
You control your beliefs, and those beliefs are informed by your thoughts. Be them thoughts produced out of emotion or ignorance. Or thoughts diligently produced after contemplation and education.
You need to make sure that you think in a matter that is conducive to your calling, not counterproductive to it.
