Everybody feels like this, and I think nobody stays ahead of the curve for a prolonged time. There's just too many wrinkles.

But also, you don't have to upgrade every iteration. I think it's absolutely worthwhile to step off the hamster wheel every now and then, just work with you head down for a while and come back after a few weeks. One notices that even though the world didn't stop spinning, you didn't get the whiplash of every rotation.
