The help of a female friend will strengthen your endeavour.
People who are famous for their talents and skills don't just magically burst onto the scene and become stars. They spend years getting preparing, rehearsing, networking and struggling, so that when their lucky break finally comes along, they feel ready to step into the light and show us what they can do. You are the same. Don't give up your preparations, otherwise you may not be ready to shine when the spotlight comes your way. Whether it's a serious dream or just a hobby, there's no reason to stop developing yourself if this is truly something that you love.
If you want to overcome work-related anxiety, focus on your goals, not your performance.
