What are the problems in your life?

The next time you sit down to write a song and find yourself having writers block, take a hard look inwards and think about the problems in your life, no matter how big or small.  People love singing songs they can relate to.  Chances are, if you have a problem or thing you're going through, lots of other people might be going through a similar issue.  Don't be afraid to write about your real life - it will make you and your listeners both feel less alone.
