Resolution in Chinese / Japanese...

決心 is a Chinese, Japanese, and Korean word that holds the dictionary definition of determination but literally means determined heart.

The first character means to determine or determined.

The second character means heart, mind, or soul, so you can imagine that this form of determination partially means putting your heart into something. It can also be translated as resolve, resolution, or decision (as in a decision made and followed).

Don't forget your first resolution.
Never forget your childlike enthusiasm.
Forget not the beginner's mind.
Try never to lose your initial enthusiasm (freshness of attitude).
