Does anyone have any unique ways to remember the NCO Creed?

The remembering will come as you honestly comprehend what you're saying and constantly reciting it. You need to believe every word of that creed because if not, you'll see no flow of context nor content. When there's no comprehension and conviction it makes it so hard to recite because you're simply reciting, rather than retaining to abide by it.

Believe what you’re reading and reciting and take note when others are following and faltering.

I generally recommend taking a copy and post it some where you go often (latrine, fridge etc.) and you read it out loud / recite as much as you can (look when necessary) before you access the area and before leaving. It forces the function and before long - you'll have it down.
