Yes, I use the same method as mentioned by you.
as mentioned by some one, as a famous poet/scholar/intellectual/historian has said/has revealed this fact.

or there's also another way.

..... "..........................quote.................. .........." (anonymous/unknown)

But I want to request seniors and any expert to guide us about this because I'm not sure about all this as well.

IF WINTER COMES,CAN SPRING BE FAR BEHIND!

Life is a mixture of sorrows and happiness. If one enjoys the happiness of his life then he also should have the courage to face the difficulties which may come in his life.
This line was written by an anonymous writer but the basic theme, the writer wants to give us is that, "Dont't get disappointed on your defeats". As these are the part of everyone's life and every night of darkness can surely see the bright light one day.
If anyone wants to prosper in his life then he should learn well how to tackle his problems and how to handle the situations which may be counted as worst period of his life? These all situations can make the man able to understand the real lesson of life and these hardships could make the faith of man more strong on his God and the bond of faith between the aggrieved and his God become more stronger.
So, no matter how far the spring be but a man of courage always stick to his cause and never undermine his morale in the course of life and after taking every hardship on his shoulder, he can achieve one day what he actually wants and that day would become the real start of spring in his life.

aoa its a good attempt,but can be even better..do examplify the idea also.if u dnt know the author's name u may rather avoid giving narrow allusions....
regards

A CONTENTED MIND IS A BLESSING KIND

A man who have vast knowledge and so many ideas in his mind and his creativity surrounds all his mind then surely it is a blessing of God on him. As Hazrat Ali (R.A) said that, "If i start writing on the word Al-Hamd of Surah Al Fatiha then hundred camels can take the load of those books", it explains the richness of knowledge which Hazrat Ali (R.A) possessed.
Pakistan is also the outcome of some rich contented minds. Allama Iqbal gave the idea of two nations, Quaid Azam also demanded a separate homeland for the muslims in the name of Pakistan, on the basis of ideas which emerged in his mind, Chaudhary Rehmat Ali suggested the name of Pakistan for the muslim's independent state. These all were based on the ideas and thoughts of the fertile and nourished minds.
Today, we also want the fertility and nourishment of mind to exterminate all those things in our system, who are harming the very basis of our motherland. The prosperity of our country is also hidden in this thing that we can persuade our youth to seek knowledge and can fill their minds with useful ideas and thoughts and can participate to make prosper this country.

Here is my effort. There is a difference in my thinking regarding the title of topic.

A CONTENTED MIND IS A BLESSING KIND

Man is a greedy animal who always struggles for more and more.Allah dislikes this kind of attitude and likes the contented mind and has shown blessing for only those who have one. Al-Quraan , Surah Al-Asar, " (1) By the declining day, (2) Lo! man is in a state of loss, (3) Save those who believe and do good works, and exhort one another to truth and exhort one another to endurance. " In the final ayah of this Surat Allah declares that endurance is one of the way of salvation, that is only achieved when you are contented. Moreover, a man who is always stirred up and is after greed is problematic to the society, since his works and objectives revolve around his own interests or a particular community, race, nationality or ethnic line , the example, in the greed , lust with the absence of contented mind world has reached to a nuclear flash point and amid terrorism threat. One the other hand, if there were a sense of content such menaces have not arrived to engulf the safety and peace of world as whole and individually as a part.Above all the absence of peace and contented mind is unable to find accurate and risk-free solutions because the biological functions of human body are not at harmony with the abnormal things that are beyond the circle of contented mind, hence a high blood pressure will not make a proper circulation of blood to mind and mind left with low energy supply would be unable to solve an issue on a its requisite merits, in such a condition mind will provide solutions which will breed numerous new problems like a Pandora.This all proved that the contented mind is the only righteous as well shrewd way to solve and face the world and life affairs and definitely it is a blessing a kind due to all benefits.

UMAR
