Ideas. I love 'em. Right now, I have an idea. I won't bore you with the details just yet (but I certainly will if it pans out, you lucky devils) but I love the feeling of an idea. Something clicks, hits... whatever... And it's all excitement and nervous energy. The idea just turns over and over in my head and, in the immortal words of the Kinks, I gotta move! Gotta do something!
Once started, I can't stop. I have to see it through. Good or bad/inspired or mediocre/for better or for worse, I have to get it out of my head. Sketch it out! Tell someone! Jot it down! It's the only way to deal with it. Otherwise, I feel I'd explode. My wife would come in the room and I'd be in a thousand pieces; destroyed by the energy of the thing.
I tend to disregard the approval of others when following an idea. I just gotta follow it where it goes. If they don't play out; oh, well... Perhaps next time, right? If this plays, I'll share. If not, oh, well... There'll be others.
