Haha, I've noticed the same thing.
My approach is in part to learn to accept that it's what I'm like, it's something that fortunately helps put bread on the table, and fighting it too much seems pointless. And the other part consists of forcibly turning it off at times, through meditation or other activities, and seeing if it actually benefits me or if I'm just trying to be something I'm not.
So far I lean towards 'accepting who I am' with the occasional and very necessary break. It's only when I become to 'meta' about this process itself that I get truly unhappy (trying to engineer my periods of non-engineering, and then to force myself to not engineer this process, and so on).
In fact, it's all the 'meta' stuff in general that seems to be a bigger problem than any of my natural urges. But I digress...
