learn to let go.

You, of all people, should already know this, don't you?
There are a lot of things in life which don't actually matter that much.
When you think back in a few years' time you are just gonna laugh at the you now, like how you are laughing at the past you.
When you face death, when you face losing someone, you will suddenly realise that everything else doesn't matter anymore as long as that person is happy and alive.
Remember?
That's what you resolved to yourself.
You wanted to be someone who can let go of less important things easily, so be her, be that someone.
Since it passed, it's gone.
Forget negative things, remember happy ones.
Jiayou.
