Do you know that feeling when you just need to show off that new trick with Expressions or generalize three different procedures? This does not have to be on Architecture Astronaut scale and in fact may be helpful but I can't help but notice someone else would implement the same class or package in a more clear, straightforward (and sometimes boring) manner.

I noticed I often design programs by oversolving the problem, sometimes deliberately and sometimes out of boredom. In either case, I usually honestly believe my solution is crystal clear and elegant, until I see evidence to the contrary but it's usually too late. There is also a part of me that prefers undocumented assumptions to code duplication, and cleverness to simplicity.

What can I do to resist the urge to write “cleverish” code and when should the bell ring that I am Doing It Wrong?

The problem is getting even more pushing as I'm now working with a team of experienced developers, and sometimes my attempts at writing smart code seem foolish even to myself after time dispels the illusion of elegance.
