The Pillars of the Earth : What does it take to build a cathedral ?

I just finished this book's happening in the Middle Ages "The Pillar of the Earth" from Ken Follet. In this novel , one of the main major character, Jack Jackson is a clever young architect who want to dedicate his lifetime in building a cathedral and I am wondering about what did it take to build a cathedral at that time :

• The fist thing he did was dreaming about it since his early ages and youthfulness
• He worked very hard to learn the job and he was specially inspired by his father in law and stonemason Tom Builder and by his unconventional mother who was unusual in knowing English, French and Latin, in being literate and living in the woods
• He traveled a lot and opened his mind to new building techniques during his Compostela pilgrimage where he met Moorish scholars and mathematicians in Toledo and helped build Saint Denis Basilica in Paris, thus learning how to build rib vaulting and pointed arches.
• He refused a secure and wealthy position ( and a good marriage as well) as stonemason in Spain because this job would have ruined his own dream.
• He came up creative ideas to raise funds for the Kindsbridge monastery and therefore for the building of the cathedral
• He protected the town and his environment by setting up a makeshift stone wall in order to discourage the attacks from the enemy
• He never gave up, remained always confident and the most important : he remained patient -It took at least thirty years to build a cathedral and most took longer because they would run out of money, or be attacked or invaded-
• He always saw the big picture but solved the problems step by step.

And then, I figured out 10 rules learning from this story in order to be inspired for outstanding demo !
