Paano mo malalaman kung susuko ka na o ipagpapatuloy mo pa? Tiwala lang. Things will eventually fall into place, just keep trying. Pero kapag wala na talagang pag-asa, tanggapin mo. Huwag mo na lang ipilit na ituloy pa kung wala na talaga, you can always start again, may darating na bago, and you can get another chance to make things right.
