The Real wealth to be acquired:

Consider a person with the following profile:

Age: In the prime of life....

Health: Super fit.

Beauty: Outstanding.

Wealth: Multi-billionaire. 

Qualifications: 3 PHDs.

Family: Has beautiful wife and children.

Social Standing: Among the most influential people in the country.

A few days later he passed away. 

His re-written profile now reads:

Age: Dead.

Health: Not applicable.

Beauty: Body decaying.

Eyes have disappeared leaving empty sockets.

Hair have fallen off. 

Wealth: Left empty handed. 

Qualifications: Soul did not qualify in anything.

Social standing: Besides a few people, everyone has largely forgotten him and are not concerned about him in any way.

Face the reality:

  This is the reality that faces one when death strikes. One is stripped of all external valuables, denuded from one's branded attire and wrapped in plain sheets of cloth, dispossessed of one's wealth, distanced from one's home and luxuries, divested of one's titles and even deprived of one's name – one is now referred to as “the deceased, “the mayyit” or “the janaza”.

Our enduring possessions:

But... there is some wealth, beauty and strength which will go along with one to the grave.

The wealth of Iman, Taqwa, sincerity, love for Allah, love for the Prophet (SAWS) and his Deen, compassion for the others, forgiveness and maintaining family ties; 

The beauty of hayaa, simplicity and good character; 

The strength of tawakkul (trust in Allah Ta'ala) and contentment – all these and other such inner values will accompany one to the grave.

They will be one's companion on the day of Qiyamah (judgement) and will pave the way to Jannah.

"Set forth to them the example of the life of this world: It is like the rain which We send down from the skies: the earth's vegetation absorbs it, but soon it becomes dry stubble, which the winds do scatter: it is (only) Allah who prevails over all things.

Wealth and children are [but] adornment of the worldly life. But the 
 enduring good deeds are better in the sight of your Lord for reward and better for [one's] hope." -Quran (18:45&46)

“The mutual rivalry for piling up (the good things of this world) diverts you 

(from the more serious things)". [102:1]

“…Are you pleased with the life of this world rather than the hereafter? But little is the enjoyment of the life of this world as compared with the Hereafter” (Quran, Al-Tawbah: 38).

“…as compared with the life of the hereafter, the life of this world is nothing but a brief passing enjoyment” (Quran, Ar-Rad: 26).

“And the life of this world is nothing but play and amusement. But far better is the house in the hereafter for those who are Al-Muttaqun (the pious). Will you not then understand?” (Quran, Al-An’aam: 32)

The Prophet (S. A. W. S.), too, clarified the value of this life in relation to the hereafter. He said, “The life of this world compared to the hereafter is as if one of you were to put his finger in the ocean and take it out again then compare the water that remains on his finger to the water that remains in the ocean” [Sahîh Muslim (2858)].

Ibn ‘Umar said: The Messenger of Allah (S. A. W. S.) took me by the shoulder and said: “Be in this world as though you were a stranger or a traveler/wayfarer.”

“Let not then this present life deceive you” (Quran, Surah Fatir: 5).

Therefore, while making a moderate effort to earn a halal living, the focus of one's heart and mind must be towards acquiring the real values and the enduring possessions.
