bad habits

Having only "found" writing a few years ago, there's plenty of bad habits I've worked through, and even more that I still have to overcome. I suppose all writers, as all teachers, tradesmen, and others who pursue other skilled occupations never stop learning. Sometimes when I write, I fall back into bad habits, especially when I write tired. Here's a few bad habits I've broken, or am trying to break:

• overuse of commas: Comma use is often quite arbitrary, but, I, tend, to, put, too, many, in, a, sentence, disrupting, flow, and making, it, hard, to read. Where only one comma is necessary in a three clause sentence, I'll put two. Was the comma in that last sentence necessary? Your call. I still fight this one.
• K.I.S.S.: I don't have an extraordinary vocabulary, but I often found myself using words that I found to be nearly colloquial, where simpler diction would have sufficed. My second year Creative Non-Fiction prof encouraged me to keep my writing "tight". Ameliorated written discourse eventuated.
• long, drawn out sentences: Thanks in large part to the first mentioned bad habit, my sentences occasionally approach lengths reserved for anacondas, challenging shots for the best of snipers, or intercontinental highways that make sense when I write them initially, but catch even the most experienced readers unaware; unfortunate, really, but sometimes, the desire to create an intricate monstrosity in which all subjects, predicates, pronouns and antecedents find tense and quantitative agreement is too tantalizing to pass up.
• Related to the last one, my rampant use of the "aside" can be distracting. In any form of writing, it's so tempting to take a step back and give readers another perspective using one of these: "--" (or a nice set of parentheses). 
• Finally, I often neglect to proofread what I right. Spell check doesn't cache all my errors, although I find that Word 2007's grammar check is more adept at finding disagreement than previous versions. Soon, Word will improve it's spelling and grammar check to an extent that will allow me to never proofread again!. In fact, if Coke Zero can give the world real Coke taste with zero calories, why hasn't Word found a way to do that yet?

Undoubtedly, I have more bad habits, but these are the worst of the worst.
