He thought up an idea. He made a plan to achieve it. There were obstacles in his path and he had to overcome them one by one, sometimes using fair, at other times unfair means. He stepped on a number of toes on his way, encountered many failures but never gave up. He made friends of people who agreed with his cause and enemies of those who opposed him. He loved things that supported his struggle and hated those that were bad for it. He ignored all the voices that criticized him and went on, unrelenting, with his held up high.
And he succeeded in the end. Only now, he does not think it was such a good idea to start with!!!
