I have committed all of these mistakes at one time or the other and I am quite sure that I slip from time to time esp with regards to #1. But one thing that I frequently do is read my own code after writing a certain amount. It may be after writing a module or after re factoring it or when I don't feel like writing any more. And reading my own code helps me uncover a lot of inconsistencies in it. I think I started reading after @edw519 said something like he reads his code everyday before going to sleep. While during writing my focus is on making the thing work when I am reading I am more critical of my code. Not as good as having a review but still helpful. Also I think reading code of other programmers is a good exercise. Reading different styles of books is already recommended to writers and I think that programmers can extract same benefit by reading code of different programmers. If nothing else at least it will develop your debugging abilities.
