I love the "Write instead of think." step. I tend to think of doing proofs as 'thinking on paper." A bit of a modern challenge to the usual idea of doing easy questions first: https://lifehacker.com/improve-your-test-scores-with-the-hard-start-jump-to-e-1790599531 Short version: 1. Try the hard problems first, but don't waste too much time on them 2. Do the easy problems 3. Go back to the hard ones to finish By starting 1, you get your brain rolling (subconsciously) on the harder problems while you are doing other stuff. Sometime it takes our brains a bit to pull stuff out of the filing cabinet.
