I agree with several suggestions given above. One, as Liam says, love the song. Two, there are many non-paying venues who would love to have you, Allan C. lists just a few. Persistance pays off. I know a local artist whose performing talents I would rate as mediocre. However, she is a hard worker and a good promoter. She does those things very well (she should be an agent). She is getting out and singing several times a week and has developed some routine gigs (like the first Friday of every month, play at this restaurant). It is her persistance that carries her. Finally, learn to live within your limitations, it is a source of creativity. I have developed a "unique" approach to some songs simply because I could not sing and play them in the traditional way.

Keep on playin' and singin'!
