Everything will be fine as long as no one is going to cry on your shoulder - you won't be so patient! You could be injured, be careful not to make sudden movements.
The day will be full of lessons to learn. You will turn an extra corner on the path to understanding.
You will get considerable support from a colleague or someone close to you. Don't work alone.
You have many things to do. Use your organizational skills to plan your work.
There's no point in screwing up something stable to show a fleeting sliver of self-confidence. It's time for you to put yourself under the microscope.
