One thing I've found through the years is it is sometimes better to try to force stuff. In this case, if a particular focal length doesn't work for you, force yourself to find out what it can do for you. For me, it's wide angle lenses. I have very little use for the 28-40mm focal lengths (on full frame, on APS-C, translate that to 15mm to 28mm), lenses in that range represent less than 10% of my images. However, I have forced myself to use them, which accounts for probably 75% of the images taken with them. At least now I know what they will do for me.
Generally, I just go back to what I know works. That means standards to short telephotos, or ultra wide angles. I just don't seem to see in between the two. I also don't get a lot of use out of my long telephotos, but I still force myself to use them from time to time, just to make sure I know what they are good for.
Sometimes, you might just surprise yourself and find a unicorn. That was my thing with the 31mm. I bought it as a standard lens for APS-C, and pretty much put it aside when I bought the K1, but I forced myself to use it at an ad hoc car show one day and found it to be very agreeable.
