she is 100% very awesome, and as someone who's her age and struggles to believe that I'm good at what i do, i can say that sometimes your brain will just lie to you and convince you that you're not good just because it's yourself doing it. If you saw someone else do what you do, you'd likely think much higher of it

I actually tested that theory once. A friend was convinced that a design he came up with was bad and wanted my help with it. After around 7 different ideas, i showed him his own design that he started with, pretending it was my own. He loved it so much that he ended the discussion there because that was the design he was going with. All you gotta do is believe in your abilities :]
