Once you allow yourself to identify with the people in a story, then you might begin to see yourself in that story even if on the surface it's far removed from your situation. This is what I try to tell my students: this is one great thing that literature can do - it can make us identify with situations and people far away.
Arrogance, ignorance, and incompetence. Not a pretty cocktail of personality traits in the best of situations. No sirree. Not a pretty cocktail in an office-mate and not a pretty cocktail in a head of state. In fact, in a leader, it's a lethal cocktail.
With Pantera, we lived through so many trend-of-the-day situations - when grunge was huge, we were still a heavy metal band; when hip-hop started getting incorporated into metal, we stuck to our guns and remained a heavy metal band very purposefully.
Letting go helps us to to live in a more peaceful state of mind and helps restore our balance. It allows others to be responsible for themselves and for us to take our hands off situations that do not belong to us. This frees us from unnecessary stress.

As far as songwriting, my inspirations came from love, life and death, and viewing other people's situations.
I see it all perfectly; there are two possible situations - one can either do this or that. My honest opinion and my friendly advice is this: do it or do not do it - you will regret both.
I make a distinction between manners and etiquette - manners as the principles, which are eternal and universal, etiquette as the particular rules which are arbitrary and different in different times, different situations, different cultures.
I grew up poor in crappy situations... various crappy situations. What kept me sane was reading and music. I had so many different literary tastes growing up, be it fiction like Stephen King or Piers Anthony or non-fiction like reading Hunter S. Thompson essays or reading the Beats. I was a huge fan of the Beat movement.
Outside of the cross of Jesus Christ, there is no hope in this world. That cross and resurrection at the core of the Gospel is the only hope for humanity. Wherever you go, ask God for wisdom on how to get that Gospel in, even in the toughest situations of life.
