“long-term optimism for difficult projects is made out of short-term pessimism... if you internalize that right up front and you're like everything's going to go wrong and then you operate accordingly you often are going to frontload whatever work you have um and and if you do that enough at the small scale you're going to have compounding wins”

Front-load short-term pessimism for long-term optimism

Wake up assuming the day will go sideways and the hard task will get harder. That mild pessimism forces you to eat the frog before noon, so when the inevitable wrench arrives you're already two hours ahead. Plan in nested scales (day → week → month → quarter), and at every layer ask "what does this look like when everything goes wrong?" Compounded daily, this is how multi-year shipping survives reality.
