Failure to finish a course of antibiotics is a small part of the problem. The plain fact is that when we use any sort of antibiotic or antiviral, the bugs attacked will evolve defenses. This is just simply inevitable, and is a sort of ongoing arms race between us and the bugs.
What can we do to help? Well, we can finish a course of antibiotics. We can also greatly improve our hygienic practices -- especially regarding hand washing and fingernails. Then there is coughing. What can I say about that? These are all peripheral and can be overdone, but they do help. Of course one thing is safe sex, where so far we have been losing the arms race, although making some progress.
It may be that vaccinations against almost everything will one day be found, and we can then depend on our bodies to fight diseases rather than pharmaceuticals. That will be a huge advance, but in the meantime we need to support the continued development of more antibiotics and so on.
The thing is, this is an old, old war. The fungi that originally made the antibiotic didn't do it for fun, and the bacteria have millions of years on us at developing resistance mechanisms against antimicrobials. We're just making the problem a whole lot worse, making the antibiotics so widespread that the little buggers that do have the genes for resistance suddenly get their chance to shine.
Fave piece of advice on antibiotics: don't bully your GP into giving you them!
