Well, we all know that self-esteem comes from what you think of you, not what other people think of you.
My dad, being a jingle writer, and my mom, being a jingle singer, they hooked me up with some people when I was a kid that worked with children's jingle singing groups. I used to sing jingles as a kid.
I encourage people to find and use the power of their voices just as much when I do not agree with those voices as when I do agree with them.
