Passion of the Nerd aka @popotoproductions3015 in The Toolbox Fallacy
This wasn't quite the toolbox fallacy definition I expected, but was a larger philosophical framing of a smaller version specific to getting things done (GTD).
Many people move from tool to tool hoping the next one will somehow "fix" things. In reality, it's having a tool and USING IT which creates progress.
Remember that it's rare that supposed innovation will be the fix, but picking a road and traveling down it will at least get you somewhere.
