...more rambling from me...
Distance runners are some of the most stubborn athletes there are. Period. They have to be, how many other groups of athletes will push themselves through something as grueling as a marathon? It's a sport that is just as much willpower as it is physical ability.
That being said, so many runners get it stuck in their head that they *have* to run every day or nearly every day. That's just a recipe for disaster for most people. I guess I've found over the years that I really don't like running much any more and there are a lot of other things you can do for fitness that compliment what running *doesn't* do for you.
Plyometrics, sports like basketball and tennis that provide lateral strength, weight training (including legs!), ect. And critical is including recovery days where you can stretch, swim, bike, whatever. Just give your body a rest.
Crosstraining is just a critical component that is missed by so many people and that physical and mental break is very beneficial in overall health and fitness and injury prevention.
It's really about your goals though. Cross training and doing other things aren't going to get you in marathon shape. It's just not going to happen. But if you want to do some moderate running, basic competition (local 5k races) and just generally be in good shape it's the way to go.
Stuff like basketball and biking (exercise and trail) still let me step out and run 23-24 minute 5k's without running a single mile per year. If I really wanted to go at it I could throw in a couple days of running a week and really improve.
Just be sure to do your body a favor and mix it up. As a former runner I know that's not an easy or fun sounding option.
