Act as a cognitive productivity coach. I am switching from [Current Task/Project details] to [Next Task/Project details]. Help me transition efficiently. First, prompt me to write a quick 2-sentence 'bookmark' of where I am leaving the current task so I can offload it from my working memory. Second, suggest a quick 1-minute physical or mental transition reset. Third, define the absolute smallest, lowest-friction first action (a 'micro-step') to start the next task to overcome procrastination. Fourth, outline the subsequent 3 steps to build momentum.
