Run-on Sentences

I don't feel like I have ever really had issues with run-on sentences. If anything, I have a problem with too much or inappropriate punctuation then anything else. The method I employ for avoiding run-on sentences is simple; I try to keep my sentences short and to the point. Now I am not saying that I have never been a victim of an errant run on sentence here and there; I have had my moments. I remember I lost 10% on a grade for a final draft of a paper in high school due to an inadvertent lack of punctuation which resulted in a run-on sentence. At the time I did not really know what a run on sentence was but I taught myself quickly and I have tried to avoid them from that point on. For people that have trouble with run-on sentences, the only advice I can give is if your sentence seems too long, try and split the thoughts up. Also, try and avoid silly punctuation errors because they can come back to haunt you like my incident in high school. I hope to consistently avoid the run-on mistake but it is likely that at some point in the future I will have one and I will make sure I get rid of it before turning in any final drafts.
