Learn to take direction and suggestions. This is one of those rules that can be hard for you if you don't like authority. If you don't like to take orders from anyone, you'd be wise to start your own business. Banter between co-workers is fine, but wait until customers aren't around. Fooling around isn't out of line, either, as long as the work is getting done and safety isn't an issue.
Some workplaces encourage their employees to have fun.
Southwest Airlines, for example, allows the flight crew to be entertaining. I remember a petite stewardess popping out of the overhead baggage compartment to begin her entertaining safety speech. When it came time to take care of passengers and keep the flight safe, however, it was clear the crew knew when to draw the line on silliness. Take some initiative. In our business, we usually have college interns working on a part-time basis.
