Transplanting a Solution: Borrowing from the Immune System

Reference domain: the immune system. Mechanisms you can borrow — ① Innate immunity: a first line of defense that acts immediately regardless of invader type. ② Adaptive immunity: it remembers an invader it once faced and responds faster and stronger next time. ③ Vaccine: it lets you experience a weak mock invasion in advance, building memory before the real thing. ④ Autoimmunity guard: it maintains an identification system so it doesn't mistake friend for foe and attack.

Pick one problem you're actually facing right now and write it in one sentence on the first line (a problem that 'collapses under an external shock'—a recurring mistake, sudden work requests, spending control—is even better). Then borrow at least 1 of the immune mechanisms above to design a solution. Must include: ① at least 2 pairs mapping elements of your problem to immune-system elements, ② 1 first action you can start this week, ③ 1 point where this analogy doesn't hold.
