Where to Go?

Recently, I seems to lose the enthusiasm of research. No mood to read, to discuss, to work on experiments. I know this is not correct way to go, but I just couldn't help become anxious. I would rather there's a problem let me to just jump in.

I don't know whether this is related to the frustration of recent progress. Too slow.

To be frank, I really doubt current development of machine learning field. Too fast. Each year, in the top level conference, there are lots of publications, but very few of them worth reading. Lots of them are just rubbish. Is this common in other fields?

I am wondering which direction should be a correct way to go. Searching in blind is really difficult:(
