I think sometimes all you need is to hear someone else say the same thing that you're going through to realize that you're not alone. I try to put some sense of hope into the songs into whatever the situation is so that it's not just dirt drudgery and a life of misery.
If I was writing songs just for me I'd only play them in my living room alone.
I want to sell to people my own age because that's the way I write songs.
I don't care half so much about making money as I do about making my point and coming out ahead.
