You change your life by changing your heart.

Have butterflies in one’s stomach

心裡七上八下

If not us, who? If not now, when?

Curiosity killed the cat

好奇心會惹上麻煩

I realized when you look at your mother, you are looking at the purest love you will ever know.

In a gentle way, you can shake the world.

Once in a blue moon

極少的情況下

Laugh one's head off

As busy as a bee

Hang in there!
