Some say that life is full of ups and downs,
just like the curve of sine waves,
but whenever, you should keep your heart in zero.
There is no need to give a clear answer to each question,
or to present an exact definition to everything.
Just do what you think the right time.
Keep yourself optimistic, confident and busy,
experience as much as possible, and this is actually, what life is.
Now that no one can escape from death, why not
take it easy and enjoy every pace of life?
