User blog comment:JustSomeDude.../The Tension Part 1: Fear of Editing/@comment-5006572-20150325171512

I just want to tell the new users reading this that an undo won't be the end of the world. Don't get demotivated by it, but learn from it. We'll always be here to explain to you what you did wrong and, like alot if things in life, through this concept of learning from mistakes, you'll eventually be able to become a great editor.

Also referencing does indeed lessen the chance of your edit being undone. If you have any questions on referencing you can ask me or the other members of the Ref Crew. We'll be more than likely to help you.
