I agree with the guys above. You're reading technique-heavy books. Try a biography, or a history of magic book - or something totally unrelated. Maybe look into classic science fiction - did you know Mario Brothers is largely inspired by the Barsoom novels?
You can also take up a new hobby, unrelated, that allows you to take a break from focusing 100% on one subject. This past year I started blacksmithing (not a cheap hobby, btw)
At a lecture by Wayne Houchin (which I highly recommend) he said that he did not get really good at entertaining with magic until he stopped obsessing over magic. When he allowed other interests to develop, he was able to work that diversity into his performance and it made that performance much more relatable to the audience.
Remember - no one is forcing you to do this. If it feels like a chore, you might need to find a way to spice it up.
Oh and one other recommendation I hadn't noticed in this thread yet - Perform. Yes we need to learn and yes we need to rehearse forever - but we also need to perform. Performing reminds us why we're doing the learning and rehearsing part.
Maybe give yourself a challenge - can you do an entertaining 5-10 minutes with nothing but self working tricks? Can you put a story to a card trick you've done forever? Can you take the first trick you ever learned, and perform it now, and see how different it is just from your enhanced skills?
