Ok, so I'm 10 years old. I've written many songs, but have rejected them ALL. Only one person has called my singing bad, and she said she was joking. My sister said I'm good 7/10 and my mom said 9/10. I want to be a singer so bad. But if I add any videos to like youtube.com, peaple might comment"wow shes stupid" or something like that. Comment if you can help me.

You could always ask for some singing lessons for your birthday, or check out a drama group for your age, they often have musicals you might get apart if you try out.

Its good practice and you will get the chance to work with someone who knows about singing.

First, you need to get some unbiased opinion about your talent. Does your school have a music department? Ask one of the music teachers.

Second, you need to develop a thicker skin. If you are afraid that people will think you untalented, you will never get anywhere. You have to develop confidence in your talent.

Third, forget (at least for now) about being a "pop star". Your goal right now should be developing your talent. Join the school chorus, church choir, local theater group etc. When you have honed your talent and have more confidence then you can start trying to promote yourself more widely.
