What are some ways to become more assertive?

Other than youtube, what are some other ways i could become a known singer?

• my mom won't let me have a youtube account because of safety issues, and i rather hold off on having a youtube account until after i get out of high school so i wont have to be paranoid about the immature kids at my school finding it. so what are some other ways i can become a well known singer? and is it possible to go to a record company and ask if they'd like to sign me? or is that not how it works? like how did singers like rihanna, katy perry, taylor swift, britney spears, etc, get discovered? also, what are some ways i can get over my stage fright?

• Answer:

  Write something, record it, and send it in. For stage fright you just need to push yourself to perform in front of others and build up self confidence. Also, just focus on what your singing not who's listening to you.
