What I have found helpful, coming from someone that now uses RoR but failed to learn it the first time around, is that you need a project in place that you are going to build using the new framework. Then you need to tell all your friends and family that you're going to launch a new web app in X amount of days, and that they should be excited about that. After establishing a foundation of peer-pressure, you will be a lot more motivated to achieve your goal with the new framework. With that in mind, it seems to me that Django, RoR, etc. are all pretty much the same difficulty to learn. It essentially boils down to some Active Record component, a MVC model, and some funny sugar here and there.
