Sound advice, as usual, from patty clink. Having a great instrument technically, is no guarantee that you will reach the audience in a meaningful way. It is much more important to understand the story the song is telling, understand the audience and venue you are in, and then sing the song. And in case you missed a very important point she made, let me restate it in a different way. It ain't about you, it's about the song/story. There is a perception these days that vocal gymnastics are the way to sing. I find them boring, and a coverup for lack of talent.

There is an analogy in guitar players. How many technically competent players have you known, that you see in sessions, and wished you could play like them? How many of them are making a living in music? Usually it is the person that can take a song, and make folks feel its story, that folks come to see.

Work with what you have. Make sure you can sing in tune relative to yourself. Find ways to interpret a story well within your voice. If you have given up already, then you wouldn't have made it anyways.
