情 means feelings, emotions, passions, and sometimes refers to the situation you are in (with your emotions).

At least, this is the definition in Chinese and Japanese. This word is a bit stronger in Korean Hanja, where it means affection, love, compassion, sympathy, tender feelings, and emotions. Just as in Chinese and Japanese, this can also refer to your circumstances or your facts of life in Korean.
情 is also the original Korean Hanja for the surname Jeong (정).

In Japanese, this can be the surname Sei.

愉 can mean pleasure, well-pleased, contented, and happy.

Note: 愉 is no longer in common use in Japanese.

動力 can be used for motivation - it can also mean power/motion/propulsion/force. It can be anything internal or external that keeps you going.

動力 is the safest way to express motivation in Chinese. If your audience is Japanese, please see the other entry for motivation. 動力 is a word in Japanese and Korean, but it means “motive power” or “kinetic energy” (without the motivation meaning that you are probably looking for).

動機 is a common word for motivation in Japanese and Korean.

In Chinese, it can have some bad connotations - so it's safer if your target audience is Japanese or Korean.

It also can mean willingness (e.g., to do something), eagerness, inspiration, determination, totally willing, fully motivated, and high aspirations.

熱情 is a Chinese and Korean word for enthusiasm that can also be translated as passion (for a cause), ardency, ardor/ardour, enthusiasm, or zeal.

Enthusiasm is being warm, cheerful, happy, and full of spirit. It is doing something wholeheartedly and eagerly. When you are enthusiastic, you have a positive attitude.

In some contexts, this could mean being extremely fond of something or having a fondness for a cause or person.

This Chinese word can also be translated as “sincere and warm” or literally “warm sentiment / affection.”

專用 is the dedication you might have to your job or a person.

Trivia: It is the same word used as an adjective in front of the word for “network” to say “dedicated network” in Chinese.

Please note: While this is a word in Korean, the meaning is private or “exclusive use.” So this is best if your audience is Chinese.

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).
