In addition to writing I study martial arts. I’m preparing for an upcoming test and part of my training involves fasting and meditation. My fast starts this evening (so I’m thinking a lot about what I’m going to eat for lunch, but that’s not what’s important… well, to you anyway).
The fast and meditation tests will power and dedication to an idea. This kind of training is intended to build discipline, self-control, focus and persistence.
Being a successful writer is no different. It’s easy to put off writing in favor of watching television or some other diversion. But as a writer you need to dedicate time to practicing your art. Writing requires focus and discipline. Many people say “you need to do it every day, and set a routine for your writing.” That may indeed be the case, but personally, I think there are as many different kinds of writers as there are people, and the ways we prefer to work are different. Figure out what works for you and make your own rules about how to keep yourself productive, and stick to them.
