obstacles to success i have and what i need to do to overcome them

Talking about what obstacles i have- successive bad singing practices, self doubt, dealing with haters who say i cannot sing ,or write- i ignore the haters, i am positive enough to overcome my self doubt, and i know i will have better day singing ,besides i am not performing for an audience ,or podcast, i am practicing ,or writing in the privacy of my home, which is not for others to hear me
