A lot of aspiring artists say they can't produce anything until inspiration strikes. I call bull. Inspiration is as illusive as the last tear off of a unicorn's eyelash. It's a fly by night lover who may or may not visit your bed today even though you'll wait until the wee hours of the morning for them to come home. In short, it can't be trusted.
But my art is crap when I'm uninspired, you cry out. Well, so what? In this creative life you're going to produce far more crap than gold. Get used to it. And most importantly, get to creating. If you start now, inspiration or not, you'll be even closer to making true gold.
