I know that I can sing really loud. It's like having that really big Evinrude engine on the back of your fishing boat. But I've been trying to be more dynamic with my voice, and not just singing on 10 all of the time out of terror.
Just remember, you can do anything you set your mind to, but it takes action, perseverance, and facing your fears.
I think that what I'm interested with is the creative side of music-making, rather than all the travelling.
