2) If your signature is a complicated scribble, did you have to spend time practicing it to make sure you get it right every time?
3) If your signature is a complicated scribble, is it legible?
To answer the first question, my signature is just my name in cursive and quite legible. Also, it's completely different almost every single time, which isn't great for me, but I can't help it. I constantly change my handwriting too, without even realizing it. I mean, are you supposed to come up with a complicated, original signature and then practice by drawing it over and over?
