The real wisdom here isn't that small beginnings matter—everyone knows that. Rather, Lao Tzu is pointing out that *difficulty itself is a variable*, not fixed. A task that seems mountainous today becomes manageable tomorrow simply because you've already begun it; the mountain shrinks as you walk. Someone putting off learning an instrument, starting a conversation, or changing careers often imagines the first step as the hardest, when in fact inaction compounds the dread. Begin when the obstacle is still theoretical, before your imagination has inflated it into something insurmountable.
