Which way is better

I was always wondering which is the best way to program for a functionality on a given language.If look at a code written two years back and if i reorient it in a better way is it evoltion or a bad program then. I can tell myself that i keep evolving everyday.

I keep thinking and acting for what will make my evolution better or what will suffice my thrist to write the best code? Can I achieve the best expression only when i know the different expressions... So where can I find the different expressions? So similar thoughts are there for any person who likes to write a good program...

So, talking about different paradigms or expressions. I found this article
Lisp is a sin from Sriram and the above atricle from Don Brox quite interesting...
