A heads up, practicing singing is not easy, and it requires a lot of patience. I believe patience is the most important thing.
I truly believe anyone can sing and it will sound special since everyone is different with their own voice and singing is a task that you can't do unless you're healthy.
It's a portrait of who you are, you are singing about you and your experiences. So it's important to eat well, be active, and have a good mindset!
