song writing?

last night me and some friends went to a mini concert last night at a school.  the performer was Jeff Black, he was absolutely great.  his songs were so pure an you could tell they were from his heart and things that he just wants people to know.  ever been somewhere or been with someone and its just been so wonderful you want the whole world to know?  i do.  that's what his songs are like.  it really inspires me to try to write songs.  i've tried before, and all i could ever do is compose things on the guitar . . . with no lyrics.  but i think my problem is that i try to hard.  sometimes  i try to force myself to write a song, when i think songs should just come to you naturally.  guitar compositions come to me like that, i'll just be playing a song and then all of a sudden i find a chord i like, then i go from there.  maybe someday i'll master the art.
