Question:

How do i know if im as good at singing as they say?

my friends and especially my ex gf have always told me I could go somewhere with singing if I were to get a band together. For as long as theyve told me, especially the ex, I felt they were just saying it to be nice and not hurt my feelings because I love music so much. I told them to be honest and they would always say I'm great and should go for it. How do I know if they're telling me the truth or not? I cant exactly tell by listening to myself because I'm not so sure what I hear is what they hear. Ahhh please help.
