An important thing that needs consideration is "What do you want to do... How do you want to musically perform? Do you want to sing? Or do you feel you would be doing it because you have to? Because you don't have to, The Pro has proven that point.

On the other hand, if you really want to sing, don't let a mediocre voice stop you. Voice training and the many things recommended on this forum really do work.

In my case, I have a very average voice, but I'm doing all the things necessary to improve my vocals... for one reason only - I love singing, close to a passion! And I've made some good progress, but it's taken practice and time.

So listen to your heart, follow your passion. Life's too short... you can make it work with or without singing.
