I am not a fan of the magical quick fix in any fiction, including fantasy, scifi and comic books. Unless Dr. Who is involved, and then only because we get to use the phrase 'Timey-wimey wibbliness' which, I'm sure you'll agree, there are not enough occasions to drop into ordinary adult conversation.
You must try to have a positive attitude. It does not matter how small a person is. One can still change the future. Size is only a state of mind. You know – it is how you use your wits that counts. Nothing can stop us, if we put our hearts into it. Anything is achievable girls, anything at all!
