The first two characters mean resolute with firm determination.
The second two characters mean reliable.

Together, this creates a 4-character expression that means dependable.

武士の一言金鉄の如し is an old Japanese proverb about the value of the word of a warrior.

Here are a couple of versions of how this can be translated:

A warrior's single word is as unchanging and reliable as gold and steel.
A warrior's promise is as dependable as gold, and his [scabbard contains] untarnished steel (a sword).

Note: Sometimes this phrase is written as 男子の一言、金鉄の如し (danshi no ichigon kintetsu no gotoshi)

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

現実主義 means realistic or practical in Japanese.

If you need a reminder to remain grounded in your life, this is a great way to do that.

誠実 is the Japanese version of integrity which can also be defined as a combination of “sincere, honest, and faithful.”

Some may also define this as “loyal” or “loyalty.” In some contexts, it can mean “genuine.” Yes, all of this meaning in just one Japanese word!

踏實 means realistic or practical.

If you need a reminder to remain grounded in your life, this is a great way to do that. 踏實 also can have the meanings of “at ease,” “down to earth,” “to have peace of mind,” “free from anxiety,” steady, or steadfast.

忠義 is another form of loyalty or devotion.

In Chinese, this is more specifically about being loyal and devoted to your friends.

In Japanese, this is more often used to mean loyalty to your country or nation.

Except for the slight difference noted above between Japanese and Chinese, this word is understood universally in Chinese, Japanese Kanji, and old Korean Hanja. It can also be used to describe devotion or fidelity.

It should be noted that this Kanji combination is being used less and less in modern Japan (this is a better choice if your audience is Chinese, though any Japanese person will clearly understand it).

規律 is a Japanese word for discipline that relays the ideas of keeping order, and observance (of rules, laws, regulations).

This is also a word in Chinese and old Korean Hanja where it suggests that you are one who follows a certain law of behavior or has a regular and dependable pattern of behavior, personal regime, or rhythm.
