Don't let yourself become so angry that you stop loving because one day, you'll wake up from that anger and the person you will be gone.

Watch this:

Didn't know how to cherish, will only end up leaving a lifetime of memories and a lifetime of regret, no amount of emotional change back that once had, no amount of words could not express the most sorrowfully hearts, all things will become unforgettable memories with the tears of inflows in the blood-engraved on my bones, can never be erased... -Mzhou Qiu
