Eya, we can't change nature but we can upgrade it to a better version. I used to be very shy too, I mean so shy that I can't express myself even when I am humiliated or cheated but I have to work on it.
I am glad for the fact that you used bridget as motivation instead of envying her. One thing most people fail to understand is that we have the potential to become anything we desire, we just need to get the right knowledge on how to go About it, then allow ourselves transform patiently through practice. I love the fact that you improved, keep it going that way.
