Anxiety does not empty tomorrow of its troubles, it only empties today of its strength.
The real sting here lies in Spurgeon's arithmetic: anxiety doesn't even accomplish what it sets out to do. Most of us assume that worrying today somehow fortifies us for tomorrow's difficulties, that it's a form of mental rehearsal or protective magic. But he shows us the con—we pay the price *twice*, surrendering today's vitality for tomorrow's unchanged troubles. Watch someone anxious about a presentation next week: they've already lost Monday, Tuesday, and Wednesday to a problem that will arrive on its own schedule, bringing no mercy for their exhaustion. The quote matters precisely because it exposes anxiety as a losing bargain dressed up as prudence.
