I don't think your allowance will take a hit over it but you will learn.
Don't just walk away because it's dirty. Don't throw in the towel because removing and reinstalling inspection panels doesn't go as fast as you want. If you weren't told to do it, DON'T! If you screw something up, admit it. If you use a tool, put it back. If you can't find one you used, find it anyway. When you wind up with extra parts and fasteners find where they go. Follow the instructions in the maintenance manual. Read twice and do once. You're not too smart to do "that." Look closely because big problems don't have to be obvious. Don't throw a tool because you got mad. Don't wear nice clothes. Have plenty of airflow and circulation in your workspace. Stay focused but take breaks when you need them.
And no matter what don't under any circumstances EVER...
Gotta go passengers just showed up.
