I lead Strategic Finance Foundations at @OpenAI, and I use Codex for everything. It all started with gaining leverage on our hardest monthly finance process ~6 months ago. Now I’m sharing 180 days of lessons on designing better work with AI — for any knowledge worker. The idea behind the series is simple: learn how to design the work. Break the problem into steps, give the right context, and know where human judgment matters. 𝗖𝗵𝗮𝘁𝗚𝗣𝗧 𝗪𝗼𝗿𝗸 𝗧𝗶𝗽 #𝟭 𝘁𝗼𝗺𝗼𝗿𝗿𝗼𝘄.
