What does your natural singing voice sound like? Try to use this to your advantage instead of fighting it. Mick Jagger doesn't have an amazing voice, but he and the Rolling Stones rode the top of the pop charts for decades because he uses his growly, high-energy style to it's fullest potential.
Singing like Adele, Beyonce, Michael Buble, and other "classic" voices generally takes years of training. While you can learn without a teacher, these voices are very hard to develop without professional help.
