The opposite of fear is love - love of the challenge, love of the work, the pure joyous passion to take a shot at our dream and see if we can pull it… - Steven Pressfield

The sword master stepping onto the fighting floor knows he will be facing powerful opponents. Not the physical adversaries whom he will fight (though those indeed serve as stand-ins for the enemy). The real enemy is inside himself. The monk in meditation knows this. So does the yogi. So do the film editor and the video-game creator and the software writer.

Resistance obstructs movement only from a lower sphere to a higher. It kicks in when we seek to pursue a calling in the arts, launch an innovative enterprise, or evolve to a high station morally, ethically, or spiritually.

The marine corps teaches you how to be miserable. This is invaluable for an artist. Marines love to be miserable. Marines derive a perverse satisfaction in having colder chow, crappier equipment, and higher casualty rates than any outfit of dogfaces, swabjockies, or flyboys, all of whom they despise. Why? Because those candyasses don't know how to be miserable.

The artist committing himself to his calling has to be miserable. The artist committing himself to his calling has volunteered for hell, whether he knows it or not, he will be dining for the duration on a diet of isolation, rejection, self-doubt, despair, ridicule, contempt, and humiliation. The artist must be like that marine: he has to know how to be miserable. He has to love being miserable. He has to take pride in being more miserable than any soldier, or swabbie, or desk jockey, because this is war, baby, and war is hell.
