'Āmir bin Qays رحمه الله said to his cousin:

"Leave your matter to Allāh (and) you will be at ease."

[حلية الأولياء ٩۰/٢]

Ibn al-Qayyim رحمه الله said:

It has been said: Sincerity is to forget the creation seeing you because of continually looking towards the Creator. Whoever adorns himself before the people with what he does not possess, has fallen from Allah’s grace.

[Madarīj al-Salikeen | 2/70]

Remember when Allāh ﷻ gives you hardships and difficulties, and you feel like you reached the bottom and there’s no point of life, that itself is the biggest sign of all. That the attainment of the Dunya will never give us solace nor any contentment. We always need a reminder that this world wasn’t made for our enjoyment.

There are two ways of reacting to when you get afflicted with any difficulty.

1) Give up and lose faith. Give up hope, motivation, happiness. Cut off from everyone, waste precious seconds of your life dwelling over the unchangeable.

2) Use this hardship to clear your vision of what’s really important. Get closer to Allah, do things that make you happy, make the best version of yourself by focusing on you. Become a positive person and become a means of hope for others.

The most successful of people have all faced numerous challenges in life. You overcome and take the good from it.

[Aminabinteharith]

Sufyān Ath-Thawrī رحمه الله stated:

"Be merciful, and you will be beloved to the people. Be pleased with what Allāh has designated for you of provisions, and you will be rich. Put your trust in Allāh (alone), and you will be strong."

[حلية الأولياء وطبقات الأصفياء (82/7)]

There is nothing more valuable than time. Our lives are short and the beating in our chests that we think about so little, will cease one day. The tireless heart, that pumps tens of thousands of times as you lie sleep, will finally rest.

“And this worldly life is not but diversion and amusement. And indeed, the home of the Hereafter - that is the [eternal] life, if only they knew.”

[Sūrah ʿAnkabūt 64]

So pain and difficulty are either (in reality) kindness and raḥmah (ie: mercy),
فالآلام والمشاق إما إحسان ورحمة

Or ʿadl (ie: justice) and ḥikmah (ie: wisdom),
وإما عدل وحكمة

Or iṣlāḥ (ie: rectification) and preparation for khayr (ie: goodness) which is to come.
وإما إصلاح وتهيئة لخير يحصل بعدها

Or they are prevention for a harm that would have been far greater.
وإما لدفع ألم هو أصعب منها

Ibn al-Qayyim, Shifāʾ al-ʿAlīl 1/250
ابن القيم، شفاء العليل ١/٢٥٠

A man was asked: How do you maintain and preserve your five daily prayers?

He said: I realized that no one would accept meeting me five times a day in all my conditions, happy, sad, broken, weak, strong except for The Most Merciful

'Abdul-Qādir Al-Jilānī رحمه الله stated:

"O my son, the calamity hasn't come to destroy you, it has only come to test your patience and faith. The calamity is the bellow of the servant, therefore, he either comes out as gold or filth."

[الآداب الشرعية والمنح المرعية (191/2)]

Indeed, this Qur'an guides to that which is most suitable and gives good tidings to the believers who do righteous deeds that they will have a great reward.

Protect yourself.
Listen to yourself.
Allow yourself to move forward.
Give yourself credit.
