Proactively seeking out new knowledge: mostly podcasts and watching what's new on github.

keeping an open mind: just because some pattern is industry proven doesn't mean its necessarily the better,

Testing: write a test describing a problem then trying to write slightly different solutions (eg. One that leverages service location, another that emphasize dependency injection..),

Forced & timed breaks: keep hydrated, don't get stuck "spinning the wheel".. :)
