Discipline. I think I heard somewhere that it's a bad word not to be used in polite society or by children under the age of 45. Anyway, the Messrs. Merriam and Webster write that discipline is "training that corrects, molds, or perfects the mental faculties or moral character." Well, alrighty, then, maybe this is a concept I should become more familiar with.
Joking aside, I do find that the more I write, the better I get and the more frequently the muse seems to sit on my shoulder. The ideas come more readily; the stories flow with greater fluidity.
There are times, though, when due to stress or exhaustion, I simply cannot sit down and work on a chapter of one of my books. On those days, I may have to satisfy myself with a carefully composed letter or even word play, first in my head, then on paper. We are like dancers, and without the discipline of practice, we become clumsy and miss our marks. Keep at it. It's not always fun, but it IS always worth it!
