The Bitter Battle

I once read two reasons that prevent us from happiness are by:

a) living in the past and
b) comparing ourselves to others.

While this constant battle often brews a bitter beast, I've recently realized a third bears equal importance/reminding:

The world is full of selfish people. Phony people. Rude people.

However...

Despite the dismal reality, don't lose yourself or your love towards it.
