It's much easier to see what's bad about code written by other people. I suggest you look at some really bad code, and then try and imagine what a superior programmer would find offensive about your code. You can always visit thedailywtf.com if you're lucky enough not to be exposed to bad code on a daily basis. My personal pet hates are copy-and-paste code, inconsistent formatting, excessively long lines, bad or non-existent naming conventions, Hungarian notation, and spelling mistakes - pretty basic stuff.
