A person may strongly desire that their car has not run out of gas, but if the gauge says the tank is empty and the car will not run any farther, then no desire in the world will miraculously cause the car to keep going.
Maaaring gustuhin ng isang tao na hindi maubusan ng gasolina ang kanyang kotse, ngunit kung wala na talagang lamang gasolina ang tangke, hindi na tatakbo ang kanyang kotse kahit gustuhin pa niya itong tumakbo.
