Just do it

Quitting my day job and starting my life as a writer was a tremendous risk, it was a fool’s leap, a shot in the dark. But anything of any value in our lives whether that be a career, a work of art, a relationship will always start with such a leap and in order to be able to make it, you have to put aside the fear of failing and the desire of succeeding. You have to do these things completely, purely without fear, without desire, because things that we do without lust of result are the purest actions that we shall ever take. - Alan Moore
Ah this might be the answer to many things. This is something crops up again and again in the lives of the successful, that they do it because that is what they do, not because they are searching for fame or wealth but because they are doing it, period.
Like the journey in a myth or saga, the hero sets out doing what is needed in the moment and in many cases they do not heed the warnings of the wise, taking them to places that are unique to their development. The use of guile and cunning, and this is particularly important in the Irish myths, often plays a part in their success. You see this in the Tolkien stories of Middle Earth where riddles need to be solved in order to progress or survive.
The aspect of doing something for the love of it not the lust of the result, being purely in the moment; which in itself is what great artists like Lou Reed, Picasso, Hendrix are doing.
The idea of doing something artistic for the doing of it seems rather odd today because some accountant somewhere needs to measure what you do, that seems to be the nature of accountability that we have entranced ourselves with, but maybe we need a dose of Alan Moore’s anarchy to get the creative juices moving.
