How can a really great work be 'produced'?

Or to put it the other way round, can it really be ‘produced’? I had been somewhat consumed with this question for a while and have been trying to understand the dynamics behind it. Einstein was the one that came to my mind. How did he produce such great corpus and what common nature such great minds have ? Was he having some special gifts that his fellow peers or normal human beings didn’t have? 

The truth is he was not a Mozart type early prodigious talent. On the contrary , he was ridiculed to be a useless fellow in his school days and he didn’t even find the job of a school teacher after his graduation. The greatest gift or talent that Einstein had was his unrelenting stubbornness and  to think abstractly. He used to visually try to find solutions to the problems that he was confronted with and to persist with a problem till he got a satisfying solution to it ( He got his famous E=MC2 equation through his persistence and patience of ten years). This nature can be found common in Beethoven, Kafka, Feynman etc. 

The thing that really comes out common with great scholars is their ability to meditate on the problem that they are confronted with and to pursue it till its completion with consuming passion. The word “passion” here is very important because for getting the right question, perseverance is required but to produce a great work, passion all the way is required. Passion can be replaced by the word ‘intense pleasure’. The indomitable spirit towards their work that  these masters had  can be considered as an  aggregation of all pleasures that a human being can desire.

The human mind or ego lives with various forms of pleasure or to put it precisely normal human beings consume eclectic pleasures. However, scholars or people who produce great work (genius) have singularity of pleasure. Their work is for them their greatest pleasure or passion. But then a question that would obviously confront us is – Can a person following the above procedures produce great work. It can be  done but that requires dedication like a zen monk or like a unrelenting maverick. This was shown in the case of Susan Polga the first female chess grandmaster. Susan's father was a psychologist and he believed in the concept that genius can be made. He trained Susan and his other two daughters to make chess their second nature and he made them to be just consumed in that from early childhood. All the three became the first three female chess grandmasters. It is the sustainable passion for the work that is important.  The production of a great work  is not a pure logical process , rather the concept of intuition plays a crucial role to achieve the end process. The subject and the object gets diluted when a great work is produced. It’s like the Zen story in which a pupil asks his master of how to produce a great sketch of a tree around, the master tells him to meditate on the tree to undo the plurality i.e to become the tree.
