Dot Your "i's" and Cross Your "t's"

Have you ever looked at your own handwriting and wondered whether it has any bearing on how you look and what it says about your personality?

No, I'm no expert at reading handwriting but I once read that one can improve one's memory by making it a point to dot your "i's" and cross your "t's" correctly instead of having that horizontal bar or that dot three miles away from the vertical stroke. You try it and tell me. Anyway, as far as I'm concerned gel pens are nicer to write with than fountain pens. But I digress.
