What's left to carry on?

I wrote this all at once, falling asleep at the summer camp I worked at; I was having a tough week with the kids being respectful, and wanted to write something to make them think in better ways. I prayed about it for awhile, and at this point, the words just flowed. I've made a few minor word changes since the original, but it's still close to what I wrote when I almost decided to just go to sleep.

When you're all dead and gone,
What's left to carry on?
What reputation have you left?
Love and hope, or pride and theft?
Virtue holds a great reward;
Selfish pleasures leave you bored.
Starved of life, you seek for joy,
Serving yourself, you stupid boy!
Integrity is man's best friend,
Honor holds true through the end.
Selfishness is wasted life,
And only causes hate and strife.
Heroes are selfless and true--
The question is,
What are you?
