How about this?
DO make the tank your personal, unique style.
DON'T inhibit yourself with rules.
While I appreciate the sentiment of a do and don't list, it's hard enough for beginners to figure out how to grow plants no matter what the scape while those with more experience generally have their own style(s) and don't need a list.
I think the most important thing for each person to remember is to express their own selves and to make the tank become whatever feels good to them. It's their tank. While learning various techniques can help us all express ourselves in our tanks, there are no rules of what a person should do or should not do other than enjoy themselves.
Couldn't agree more.
