Hi,
You have many great things going for yourself.
I have learned to listen for my own insecurity, stop it, and use positive self-talk.
It takes practice, and will result in more self confidence.
I believe you can do it, and overcome your difficulty.
I have been in my trade for nearly 30 years and still make plenty of mistakes.
We all do, but you shouldn’t let it get you down.
You seem to be a bright, aware individual with a bright future.
Hope this helps!
