How do I stop replaying my old favorites and discover some new games?

Don't bother. You'll just have a backlog of mediocre games you don't actually enjoy and will never get through. At best you'll broaden your horizons, you already know what you like and you know you're not going to find it in more games you feel like you ought to try.

Save yourself the money and the stress, because all you'll do is want to go back and play the games you already love and know you enjoy, and there's no point to forcing yourself to play games you won't actually enjoy.

I can't agree with that simply because I actually have had positive experience of greatly enjoying new games because I forced myself to play them at first.
The problem is: I often find myself lacking the strength to make that first initial push to start playing a new game or play it past the beginning. And I'm actually interested in getting into those games.
I guess it's a general problem of the lack of willpower, rather than a vidya problem in particular.
