Codes-Expression of your grey matter

Well codes that we write daily, I believe is what we have within us. Imagine for a program to calculate an addition of two numbers, everybody will write the codes in the manner that is unique from each other. This uniqueness is what defines your grey matters. How efficient and distinct is your code from others? Its been long time ever I have seen two snippets of codes for same problem by two different persons are same, even if they are it will differ by one semicolon at least.
Order of the day, to write better and efficient codes I believe one has to tune up the curves of your 800gms substance in your head.
