Usually if something is interesting it&#x27;s because you&#x27;re thinking about it in the context of a problem that you need to solve. Basically, it&#x27;s interesting because you see the potential value.<p>That generally is what drives what I learn. I&#x27;m about to start getting deep into BPM2 and Activiti because it looks like it will solve an organizational problem that I&#x27;m currently observing, just as an example. Otherwise it&#x27;s not really connected to anything I would be doing otherwise (although there are a few potential use cases if I understand the system the way I think I do).
