Very, very true.
In fact, what you say is scientifically true as well.
The thoughts that we think eventually come back to us in the future. Call it karma, or call it feedback - but it does happen inevitably.
That's why I have a love/hate relationship with the hateful messages that I see on here.
On one hand, I am shocked by them, and I feel pity for the people who post them.
On the other hand, I LOVE IT when people express hatred for Obama or whomever, because they (the ones posting the messages) embarrass themselves in front of everyone that reads these boards.
Cheers.
