Life is like a sine graph,
no matter how far you fall,
it will reach a time that you hit the minimum point.
That's when the gradient will become positive,
and you'll see the silver linning.

i guessed it's really true. in life, there are always ups and downs. so.. we shall be strong when we're down and there's always a turning point when everything will just turn out to be fine.
