In most cultures singing is a prominent part of the society. It is a hobby that can both expand your horizons and connection with the world around you. If you are too conscious to go for private singing lessons, start in a local choir so that you can hide for the first few weeks before taking center stage.
You never know, by starting this hobby you could find that you have a hidden talent you never knew about. It is a very impressive skill to have, and when you want to impress that special someone you might actually find that it becomes your X-Factor.
