Some will translate it as a suggestion to be assiduous and long-suffering.

My favorite is to use this to remind myself to be hard-working and capable of overcoming adversity.

Figuratively, this means:
One who has gone through hardships is not afraid of (minor)setbacks.

In Chinese, Japanese Kanji, and old Korean Hanja, 克服 means “overcome” (as in overcoming hardships, etc.). It can also mean to conquer, to put up with, or to endure.
This can be a conquest over a problem, disease, handicap, poverty, or illness. Other definitions include overcoming, bringing under control, subjugation, or victory over something.

This can be used as an inspirational wall scroll to remind someone to try to overcome difficulties that may arise in life.

欲樂 is the Chinese and Japanese title representing the Buddhist and Jainist joys of the five desires.

Kama comes from the Pali/Sanskrit काम. The meaning is “desire, wish, longing.”

In Jainism, it can include sensual pleasure, sexual desire, and longing.

However, the Buddhist context refers more to any desire, wish, passion, longing, the pleasure of the senses, desire for, longing to and after, the aesthetic enjoyment of life, affection, or love, enjoyment of love is particularly with or without the enjoyment of sexual, sensual and erotic desire, and is often used without sexual connotations.

不磕不碰骨頭不硬 is a Chinese proverb that literally translates as: Without being knocked around a bit, [one's] bones won't become hard.

Figuratively, this means: One can't become strong without first being tempered by “hard knocks.”

While true for everyone, this sounds like the “Iron Body” form of Kung Fu, where practitioners' bodies are beaten (and often bone fractured) in order to become stronger.
For the rest of us, this is just about how we can be tempered and build character through the hardships in our lives.

This is not a common title for a wall scroll in China.

世事難料 is a polite Chinese version of “shit happens.” This phrase suggests that things happen (for no reason, and for which we have no control).

The first two characters mean the affairs of life, things of the world, worldly affairs, or ways of the world.

The third character means disaster, distress, problem, difficulty, difficult, hardships, troubles, or defect.

The last character in this context means: to expect, to anticipate, or to guess.

If you put this back together, you have something like, “In life, troubles [should be] expected.”
