I'm really excited for you, in all seriousness. I have a massive fear about this, that one day I'll need to stand up for myself or someone I care about and I need to be assertive and I get stuck on what I'm saying or that I'm so focused on how I'm talking that I don't think ahead enough and lose my train of thought. It's nightmare inducing stuff. But this is truly awesome. This just shows you that you are stronger than you think you are and capable of much more. Keep pushing yourself and putting yourself in difficult situations, and pushing the boundary of what is comfortable. I think our worse enemy is often ourselves.
