Life doesn't stop, time cannot be still, yet you can get tired. Sleep is not for the weak, and being weak doesn't mean you aren't strong. You're only human, so don't stop your life, don't wonder if you could reverse time to change something, just sleep, and be ready for the next day's challenges.
Seeing is not always believing. You can't see hope, but you can believe in it. You can't see love, but you can feel it. You can't see happiness, but it will come to you eventually.
One way to live is happy. Love yourself and others around you. Nothing is forever, not even the darkness.
