In addition to the responses you've already had, I would highly
recommend you get ahold of the book “Code Complete”, which gives
excellent, reasoned advice on how to perform the line-by-line craft of
programming.

Read it cover to cover, and you will not only improve your programming
skill, you will also be able to explain to yourself *why* some styles
are better than others.
